Preliminary Requirements

Prior to running the program, a number of environment variables should be set. These are normally set by default by running the /home/sage0/programs/.egretrc file from the user's .cshrc file. The specific environment variables that are needed and their respective default values are:

   EGRET_DIR .......................... /analysis1
   EGRET_PROGRAMS ..................... /home/sage0/programs
   FITS_DIR ........................... User writable FITS directory

To manually set an environment variable, use the setenv command e.g.

setenv FITS_DIR ~userid/fits

The program will use these variables to access executables and I/O files as follows. It must also be able to write the namelist.map file under the current directory to store the user input in a namelist.

   EGRET_DIR/bin/transmap ............... User input program
   EGRET_DIR/bin/transmap.exe ........... Main program
   FITS_DIR/counts.vp*.g* ............... FITS input counts file
   FITS_DIR/exposr.vp*.g* ............... FITS input exposure file
   FITS_DIR/intens.vp*.g* ............... FITS input intensity file
   FITS_DIR/counts.vt*.g* ............... FITS output counts file
   FITS_DIR/exposr.vt*.g* ............... FITS output exposure file
   FITS_DIR/intens.vt*.g* ............... FITS output intensity file
   EGRET_PROGRAMS/sequence/fits.seq ..... FITS sequence file
