Usage

The following gives the various command lines for running the program.

• omsource In this case the program will prompt the user to select an image file, either from a list of previously assessed files or from a directory. When the main window is displayed the user will also be able to select an existing source-list file by clicking on the load source-list button. She can also load another image by clicking on the load image button.

• omsource imageset=... newsrclistset=... For creating a new source-list file (no parameter oldsrclistset specified). The image stored in the image file specified by the parameter imageset is displayed and the user can then either select sources manually, or run the SAS task omdetect to detect sources. The created source-list will be stored after clicking on the exit button.

• omsource imageset=... backgroundimageset= The image stored in the image file specified by the parameter imageset is displayed without any source regions shown. The user can either select sources manually, or run the SAS task omdetect to detect sources. Again,the user can load a source-list by clicking on the load source-list button. When aperture photometry is performed the image specified by the parameter backgroundimageset will be used. This may be particularly useful for FAST mode photometry, in which a larger image can be used to obtain the background.

• omsource imageset=... newsrclistset=... wdxset=... This is similar to the previous case, except that the wdxset parameter has been used. This parameter is needed when running omsource on images reduced using SAS software versions prior to 5.4.

• omsource imageset=... oldsrclistset=... newsrclistset=... The sources stored in the source-list file specified by the parameter oldsrclistset are loaded the image file specified by the parameter imageset is displayed with the source regions overlaid. Each source is numbered.

• omsource imageset=... oldsrclistset=... newsrclistset=... wdxset=... Same as before, except that the wdxset parameter has been specified, which is needed when running omsource on images reduced using SAS software versions prior to 5.4.

• omsource wdxset=... Same as before, except that the wdxset parameter has been specified, which is needed when running omsource on images reduced using SAS software versions prior to 5.4.

• omsource oldsrclistset=... As before, except that the user wishes to modify an existing source-list file.

• omsource oldsrclistset=... wdxset=... Same as before, except that the wdxset parameter has been specified, which is needed when running omsource on images reduced using SAS software versions prior to 5.4

  When the program is running the user can load a new image/source-list file at any time. When the user exits the program and the parameter newsrclistset was omitted from the command-line and changes to source-list have been made, the program will display a text-input box allowing the user to type in the name of the new source-list file.
