XRTEXPMAP

Constructs a PSPC exposure map for a given energy band. The program uses the header file created by XRTCONV plus the attitude and event rate files. The output is a 512 square exposure map of the whole field. This can be transformed using REBIN using the axis cloning option to trim the map to any particular size.

The program is essentially unchanged from the Steve Snowden original, apart from adopting ASTERIX conventions on use of good time slots. This means that there is a rather limited selection of energy bands available and it is important only to apply the exposure maps to data XSORTed using the same band.
