The forward code uses SolarSoft IDL: "Solar soft tree installation instructions"

If you are installing SolarSoft for the first time, choose the following packages: forward, chianti, xrt, eit, trace, secchi, aia, pfss, swap, lasco.
(NOTE: especially if you are running Windows, you may need to first "Install Perl")

Add FORWARD (if you already have SolarSoft)

  1. If you have an old manual FORWARD install, remove those codes and also remove or comment out any system environment assignments
  2. Make sure your SolarSoft is up to date. If there is any question, do the following from SSWIDL prompt:
    • IDL> ssw_upgrade,/gen,/spawn,/loud,/passive_ftp
    • IDL> exit
    • % source $SSW/gen/setup/setup.ssw # from command line
  3. Restart SSWIDL, and install FORWARD, also install (or upgrade if you have them already) linked packages
    • IDL> ssw_upgrade,/spawn,/forward,/chianti,/xrt,/eit,/trace,/secchi,
    • IDL> exit
    • % source $SSW/gen/setup/setup.ssw # from command line

(note you can also use the Solar soft web interface to add these packages).

List all of the IDL packages in SSW_INSTR (via setenv SSW_INSTR, for example in a .cshrc (Unix/Linux) or .bat (Windows) file.
  1. For Unix/Linux, setenv SSW_INSTR "forward chianti xrt eit trace secchi aia pfss swap lasco".
  2. For Windows, set SSW_INSTR=forward chianti xrt eit trace secchi aia pfss swap lasco.
