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
   EXPHST_DIR ......................... EGRET_DIR/data/exphst
   MISC_DIR ........................... EGRET_DIR/data/misc
   CALIB_DIR .......................... EGRET_DIR/data/calibration
   FITS_DIR ........................... User writable FITS directory

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

setenv FITS_DIR ~albert/fits

The program will use these variables to access executables, window 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/intmap ....................... User input program
   EGRET_DIR/bin/intmap.exe ................... Main program
   FITS_DIR/counts.vp*.g* ..................... FITS counts file
   FITS_DIR/exposr.vp*.g* ..................... FITS exposure file
   FITS_DIR/intens.vp*.g* ..................... FITS intensity file
   EXPHST_DIR/exphst.v01p* .................... Exposure history file
   MISC_DIR/timeline .......................... Timeline file
   EGRET_PROGRAMS/sequence/scale.factor ....... Exposure Scaling factor file
   MISC_DIR/pdbpre/cntl/name2 ................. SAGE namelist file
   CALIB_DIR/catlog ........................... Calibration files catalog
   CALIB_DIR/edpfile* ......................... Calibration files 1
   CALIB_DIR/sarfile* ......................... Calibration files 2
