After entering IDL and invoking KBURST, the user must respond to whether a new pointing direction is being used or whether a previous run is to be used. In the former case, a GUI appears for the user to enter input.
The program then loops through each selected viewing period. For each viewing period, three fortran programs are spawned from IDL. XPOSE calculates the exposure, EXPRD reformats the binary output to an ASCII format and finally KB breaks down the exposure by orbit and calculates the number of gamma-rays detected from the selected pointing direction per orbit.
If an existing data file is used from a previous run, a widget similar to the standard IDL routine PICKFILE will appear. Note: When specifying a new path in this widget, no ' ' or environment variables are allowed. A previously created result file should be selected and if desired, more than one result file may be selected. Multiple files will be concatenated.
Plots are then created. If time is plotted in a calendar format, UTPLOT is used. UTPLOT is a set of procedures maintained at GSFC by R. Schwartz (HSTX). Before exiting the user has an option to plot any individual plot or all three plots to a page. The post script output will automatically be sent to the default printer.
