Program Description

The PTEXPO program runs in 2 major sequences which are the input phase and the computation phase. The input part is performed with XView which allows for full screen input, default values, selection from scrollable lists and option to quit at any time. The XView window also tend to minimize the amount of typing and are fairly self-explanatory.

The core of the program will read the user input from the namelist file, read the timeline file and the exposure history file that matches the user time range is found. The exposure history file is read, the SENSTV routines are called and the exposure bins are accumulated for each file entry. The final exposure is written on the screen and on the program report.
