Usage

The following gives the various command lines for running the program. Note that the mandatory parameters imageset and newsrclistset can be omitted- the program will display a file dialog box allowing the user to select an image file , followed by a text-input box allowing the user to type in the name of the new source-list file.

The task is started running by typing one of the following commands and pressing return-

• 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 without any source regions displayed. The user can either select sources manually, or run the SAS task omdetect to detect sources.

• 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 In this case the program will display a file-dialog box to get the name of the imageset file and one to get the name of the newsrclistset file.

• 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

The task starts up by displaying a small progress-dialog box whilst it is doing some initialisation work. The image file is displayed using ds9. The main task window is displayed and the user can either select to manually select sources from the image, or run the sas task omdetect to locate sources on the image, by clicking the appropriate button. In the former case the task window is hidden and a small window appears with instructions on how to select sources. In the latter case, a small window is shown which allows the user to change the default input parameter values to omdetect. Once done, this window is closed and is replaced by another one indicating that omdetect is running. For both cases, when finished, the main window is shown and the user can then proceed to either examine the parameters of a particular source, by selecting a particular
