 <h3>Base de donnée de fichiers FITS/XISF</h3>
 <p>Tenmon peut analyser un répertoire de fichiers FITS/XISF et indexer les métadonnées des en-têtes FITS dans sa base de données interne. Cela permet de rechercher et de trier des images en fonction de ces métadonnées.</p>
 <p>Pour remplir la base de données, sélectionnez un répertoire de fichiers FITS/XISF avec <i>Fichier->Indexer le répertoire</i>. Une fois le répertoire parcouru, les métadonnées analysées à partir des images seront stockées dans la base de données. Pour actualiser la base de données, exécutez <i>Fichier-> Ré-indexer les fichiers</i>. Cela mettra à jour toutes les métadonnées modifiées et supprimera tout enregistrement de fichiers supprimés. Pour indexer de nouveaux fichiers, exécutez simplement à nouveau <i>Fichier->Indexer le répertoire</i>.</p>

Pour ajouter le panneau de base de données à la vue, basculez <i>Fenêtres encrables->Base de données FITS/XISF</i>.

+Ces trois boîtes contiennent la liste de toutes les propriétés qui sont trouvées pendant l'indexation, sauf les trois premières. La première définit la recherche dans le nom du fichier.
+Les deux suivantes "RA pos" et "DEC pos" permettent de filtrer les images indexées qui contiennent un point avec les coordonnées RA/DEC entrée. Le format attendu est trois nombres séparés par un espace. 
+Dans le cas de "DEC pos", il accepte également le signe +-. L'omission d'un ou deux derniers chiffres est également valable. Quelques exemples "02 12 32" "-12 43 12" "+45 32" "13".
+Le fait de définir à la fois "RA pos" et "DEC pos" peut renvoyer des images qui ne contiennent pas le point saisi, car la recherche est faite sur les coordonnées RA/DEC minimum et maximum que les images contiennent.
+"RA range" et "DEC range" filtrent les images dont les coordonnées centrale se trouvent dans la plage saisie.
