The user input are performed through XView windows which allows for
full-screen input, and runs in a user-friendly manner.
The user is required to provide the coordinates of the input point, the
coordinate system, the time range of the exposure, the energy range, the
spectral index, the event class, the earth cutoff angle and a scaling
factor. Default values are provided where appropriate. The user may request
that intermediate exposure values be printed at regular intervals in
minutes. He may also generate a file of exposure values in binary format for
each entry in the exposure history file.
The program also needs the wall distance needed by the SENSTV1 routine
and reads it from the SAGE namelist normally found in
The PTEXPO program uses 1 input window shown in figure 1 (larger).
