+<h3>Plate Solving</h3>
+<p>This module can plate solve images and update FITS header with solution for FITS and XISF images.
+<b>Profile</b> this set various parameters that affect star extraction and solving.
+<b>Starting point</b> program will try to automatically determine optimal starting point which helps to speed up solving.
+You can leave one or both unchecked then it will attempt to do blind solving. If the position or scale is wrong it can actually
+fail to solve.
+<b>Solution</b> this section contain resulting solution like RA,DEC coordinates center of image, image field of view, orientation as degrees E of N,
+image scale in arcseconds per pixel, number of stars extracted and HFR fitting and eccentricity. Then there is log window for debug information from
+solver.
+</p>
+<p>Then finally there are various action button. Settings button show dialog where you can set path to existing index files or auto download some.
+Extract button will just extract stars from image and it will show their count, HFR and eccentricity. This action doesn't need index files.
+Solve button will try to find coordinates of images. Abort button will stop extraction or solving. Update FITS header will update FITS fits keywords
+with found solution.
+
+<p>In settings dialog you can set path to index files which is by default custom internal one. It also try to locate commonly used path from other
+programs like KStars for astrometry.net index files.
+</p>
+
+<h3>Batch processing</h3>
+<p>This module allow to write scripts in JavaScript that process image files. Batch Processing window consist from three main parts. On top is list of input files and directories.
+You can add directories or individual files to this list. Directories are scanned recursively to find all files even non image files. This list of files is then passed to script in array named <b>files</b>.
+In script you can then iterate through files like this.</p>
+<pre>for(file of files)
+{
+    if(file.suffix() == "fits")
+    {
+        core.log(file.fileName());
+        file.convert(file.relativeFilePath(), "XISF");
+    }
+}
+</pre>
+<p>Bellow this list is output directory. All relative paths passed as arguments into methods like copy(), move() or convert() will be relative to this output directory. If you pass absolute path to methods then
+this output directory is ignored.</p>
+
+<p>Bellow that is list of scripts. These scripts are located in application data directory. Select script which you want to run by clicking on it. Clicking on <i>Open scripts</i> will open directory with these scripts where you create new and edit them.
+Location of this directory is on Windows: "C:/Users/&lt;USER&gt;/AppData/Roaming/nou/Tenmon/scripts"  Linux: "~/.local/share/nou/Tenmon/scripts" MacOS: "~/Library/Application Support/nou/Tenmon/scripts"</p>
+
+<p>Next is Log windows that contain any messages that come from scripts. Mainly calls to <code>core.log()</code> At bottom there buttons that can start or stop execution of selected scripts.</p>
+
+<h4>core</h4>
+<p>There is global object called <b>core</b> that have these methods.</p>
+<ul>
+<li><b>log(message)</b> print message to log window.</li>
+<li><b>mark(file)</b> mark file same way as in GUI. Takes object of type <i>File</i> as argument.</li>
+<li><b>unmark(file)</b>  unmark file same was as in GUI. Takes object of type <i>File</i> as argument.</li>
+<li><b>isMarked(file)</b> check if file was marked.  Takes object of type <i>File</i> as argument.</li>
+<li><b>setMaxThread(maxthread)</b> set maximum number of concurrent thread when doing asynchronous task.</li>
+<li><b>sync()</b> wait until all asynchronous tasks are done.</li>
+<li><b>getString(label = "", text = "")</b> show dialog box to get string value from user. String value passed in first argument is used as description label. Second argument text is default value in text box.
+        Both parameters are optional so calling just <i>getString()</i> is valid. When cancel is pressed it return Undefined.</li>
+<li><b>getInt(label = "", value = 0)</b> show dialog box with input box to retrieve integer value. String value passed in first argument is used as description label.
+        Second parameter is default value in input box. Both parameters are optional. When cancel is pressed it return Undefined.</li>
+<li><b>getFloat(label = "", value = 0, decimals = 3)</b> show dialog box with input box to retrieve decimal value. String value passed in first argument is used as description label.
+        Second parameter is default value in input box. All three parameters are optional. When cancel is pressed it return Undefined.</li>
+<li><b>getItem(items)</b> show selection dialog which allow to select one item from array of items. It return selected item as string. When cancel is pressed it return Undefined.</li>
+<li><b>setStartingSolution(solution)</b> with this you can set starting point and image scale. It accepth object with attributes "ra", "dec", "pixscale".
+        Same object as returned by <i>File.solve()</i> method. You can also call it without paramer in which case it will clear any previously set values.</li>
+<li><b>getSolverProfile()</b> return solver profile as Object.
+<pre>var profile = core.getSolverProfile();
+core.log(JSON.stringify(profile));</pre></li>
+<li><b>setSolverProfile(index)</b> set solver profile by index. Valid values are from 1 to 8 as in GUI.</li>
+<li><b>setSolverProfile(profile)</b> set solver profile. Parameter is same as object returned by <i>getSolverProfile()</i> method</li>
+</ul>
+
+<h4>File</h4>
+<p>In <b>files</b> array there are instances of type <b>File</b> objects that have these methods.</p>
+<ul>
+<li><b>fileName()</b> returns the name of the file, excluding the path.</li>
+<li><b>absoluteFilePath()</b> returns an absolute path including the file name.</li>
+<li><b>absolutePath()</b> returns an absolute path without the file name</li>
+<li><b>relativeFilePath()</b> return relative path including file name relative to directory that was in list of directories to be scanned. For example you add C:/images as input directory. In this directory there
+        is file <i>C:/images/lights/red/M42_001.fits</i> then this method will return <i>lights/red/M42_001.fits</i></li>
+<li><b>relativePath()</b> return same path as previous method just without file name. <i>lights/red</i></li>
+<li><b>baseName()</b> return file name up to the first dot. For example for <i>some.file.name.fits</i> it will return <i>some</i></li>
+<li><b>completeBaseName()</b> return file name up to the last dot. For example for <i>some.file.name.fits</i> it will return <i>some.file.name</i></li>
+<li><b>suffix()</b> return string after last dot in file name. For example <i>fits</i></li>
+<li><b>size()</b> return size of file in bytes.</li>
+<li><b>fitsKeywords()</b> return array of strings with every keyword that is in header. <i>SIMPLE,BITPIX,NAXIS,NAXIS1,NAXIS2,EXTEND,COMMENT</i></li>
+<li><b>fitsValue(key)</b> return value for keyword. In case that there is multiple occurrences it return last one.</li>
+<li><b>fitsValues(key)</b> return array of values for keyword.</li>
+<li><b>fitsRecords()</b> return array of objects with properties <b>key, value</b> and <b>comment</b> </li>
+<li><b>modifyFITSRecords(FITSRecordModify)</b> modify FITS header by adding, removing or updating FITS record. Return true on success. Refer to <i>FITSRecordModify</i></li>
+<li><b>isMarked()</b> return true if file is marked.</li>
+<li><b>copy(newpath)</b> copy file to new location. It return instance of new <i>File</i> object that represent this copied file. This path can be relative or absolute. In case that <i>newpath</i> parameter is relative
+        path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can absolute path. File is then copied to this path. In case that copy fail it return null.</li>
+<li><b>move(newpath)</b> move file to new location. It return false if move failed. This can happend if destination is not writable but also if destination file already exist. This functions does not overwrite existing file.
+        This path can be relative or absolute. In case that <i>newpath</i> parameter is relative path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can be absolute path.
+        File is then moved to this path.</li>
+<li><b>convert(outpath, format, params)</b> convert image file from any format that program is able to open into FITS, XISF, JPEG, PNG, BMP.
+        Parameters are: <i>outputpath</i> path where converted image will be saved. It automatically replace suffix according to format. This method return new instance of <i>File</i> that point to converted file.
+        <i>format</i> one of "FITS" "XISF", "JPG", "PNG", "TIFF" or "BMP".
+        <i>params</i> object with attributes

+        <li>"compressionType" for FITS format it can be "gzip" and "rice". For XISF it can be "zlib", "lz4", "lz4hc", "zstd", "zlib+sh", "lz4+sh", "lz4hc+sh", "zstd+sh"</li>
+        <li>"binning" any integer value above 1 will perform integer downsample</li>
+        <li>"average" by default set to true. If you set to false it will sum pixel values instead of averaging when performing binning.</li>
+        <li>"resize" downsample image to defined width and height by subobject <code>"resize":{"width": 128, "height": 128, "aspect":"keep"}</code>
+        "aspect" determine how to handle aspect ration when resizing image. "keep" and "expand" preserve original aspect ratio. Difference is that "keep" resulting image will be at most requested size
+        "epand" resulting size will be at least requested size. For example input image 800x600 pixels and resizing to 128x128. With keep resulting image will be 128x96 while with epxand it will be 170x128.
+        If set to "ignore" then resulting image will be exact size 128x128 ignoring original aspect ratio. By default keep is used.</li>
+        <li>"autostretch" when set to true it apply automatic stretch function to pixel values. By default it is set to false.</li>
+        </ul>
+        In case that both binning and resizing is set binning is performed first then resing.

+<h3>Traitement par lot</h3>
+
+Ce module permet d'écrire des scripts en JavaScript qui traitent des fichiers images. La fenêtre de traitement par lots se compose de trois parties principales. En haut se trouve la liste des fichiers et répertoires d'entrée.
+Vous pouvez ajouter des répertoires ou des fichiers individuels à cette liste. Les répertoires sont analysés de manière récursive pour trouver tous les fichiers, même les fichiers non image. Cette liste de fichiers est ensuite transmise au script dans un tableau nommé  <b>files</b>.
+Dans le script, vous pouvez ensuite parcourir les fichiers comme ici.
+<pre>for(file of files)
+{
+    if(file.suffix() == "fits")
+    {
+        core.log(file.fileName());

+<li><b>move(newpath)</b> move file to new location. It return false if move failed. This can happend if destination is not writable but also if destination file already exist. This functions does not overwrite existing file.
+        This path can be relative or absolute. In case that <i>newpath</i> parameter is relative path then it "Output directory" from GUI windows is used as base directory. Parameter <i>newpath</i> can be absolute path.
+        File is then moved to this path.</li>
+<li><b>convert(outpath, format, params)</b> convert image file from any format that program is able to open into FITS, XISF, JPEG, PNG, BMP.
+        Parameters are: <i>outputpath</i> path where converted image will be saved. It automatically replace suffix according to format. <i>format</i> one of "FITS" "XISF", "JPG", "PNG", "TIFF" or "BMP". <i>params</i> object with attributes "compressionType" and "compressionLevel".
+        Valid values for compressionType are be "gzip" or "rice" when converting to FITS. When converting to XISF compressionType can be "zlib", "lz4", "lz4hc", "zstd", "zlib+sh", "lz4+sh", "lz4hc+sh", "zstd+sh".
+        It is recommended to use "+sh" variants of compression.
+        XISF format also accept "compressionLevel" in range 0-100 where zero is fastest compression and 100 slowest. If you omit this attribute or set it to -1 then default compression level will be used.
+        It return new instance of <i>File</i> that point to converted file.
+<pre>file.convert("converted_file.xisf", "xisf", {"compressionType": "zstd+sh", "compressionLevel": 70});
+file.convert("converted_file.fits", "fits", {"compressionType": "rice"});
+file.convert("converted_file.jpg", "png");</pre>
+</li>
+<li><b>convertAsync(outpath, format, params)</b> same as previous method but it does conversion in separated thread asynchronously and in parallel. Before calling any method on object returned by this method you must call
+        <code>core.sync();</code> to ensure that conversion is done and destination file exists.
+        <pre>let compression = {"compressionType": "zstd+sh"};
+let convertedFiles = [];
+for(file of files)
+{
+    if(file.suffix() == "fits")
+        convertedFiles.push(file.convertAsync("xisf/" + file.fileName(), "XISF", compression));
+}
+core.sync(); // ensure that files exist
+for(file of convertedFiles)// now we can iterate over the files
+{
+    core.log(file.fileName() + " " + file.size()); // let print compressed file sizes
+}</pre></li>
+<li><b>stats()</b> calculate basic images statistics and return them as object with attributes "mean", "stddev", "median", "min", "max" and "mad".
+<pre>let s = file.stats();
+core.log("Median value is " + s.median);</pre></li>
+<li><b>solve(updateHeader)</b> this method will run plate solving on this image and will return solution in form of object with these attributes "ra" and "dec" which are center coordinates of image
+        "fieldWidth" and "fieldHeight" which is FOV of image in arcseconds, "orientation" is degrees east of north, "pixscale" scale of image in arcseconds per pixel,
+        "parity" true false value if the image was flipped in vertical direction, "raError" and "decError" deviation from starting point.
+        When updateHeader is set to true it update FITS header for file with this solution. Default value is false.</li>
+<li><b>extractStars(hfr)</b> extract stars will run extraction of stars. When parameter hfr is set to true it will fit HFR on every star.
+    It return array of objects representing extracted stars. Each object in array
+    will have these attributes "x" and "y" pixel coordinates of center of star, "mag" relative magnitude of star, "flux" total flux, "peak" peak value of star, "HFR" half flux radius of star,
+    "a" and "b" semi major and minor axis of star, "theta" angle of orientation of the star, "ra" and "dec" coordinates of star, "numPixels" number of pixel occupied by the star in image.</li>
+</ul>
+
+<h4>FITSRecordModify</h4>
+This class is used to define modify operation FITS header in FITS and XISF files. It can remove update and add records. Order of operation is also remove then update and last add.
+The keyword names may be up to 8 characters long and can only contain uppercase letters, the digits 0-9, the hyphen, and the underscore character.
+<pre>let modify = new FITSRecordModify();
+modify.updateKeyword("OBJECT", "M42");
+modify.updateKeyword("MYTILE", "PART1", "adding custom keyword so WBPP can group it");
+modify.removeKeyword("OBJECT");
+// doesn't matter that it is specified as last. This will first remove
+// existing OBJECT record and then add again OBJECT=M42
+for(file in files)
+{
+    file.modifyFITSRecords(modify);
+}</pre>
+
+<ul>
+<li><b>new FITSRecordModify()</b> create new instance of object.</li>
+<li><b>removeKeyword(key);</b> specify removing of record with <i>key</i> as keyword.</li>
+<li><b>updateKeyword(key, value, comment = "")</b> specify updating existing keyword with value and comment. Comment is optional parameter. If record with keyword doesn't exist then it will add new one.
+        Unless you want to have multiple records with same keyword (for example HISTORY) always use this method and not addKeyword.</li>
+<li><b>addKeyword(key, value, comment = "")</b> specify adding new keyword</li>
+</ul>
