Environment Variables

  See the section 2.2 for information on setting up the proper CALNICC_BASE environment variable. Below is a description of the environment variables automatically set when Calnic C is run, along with those that should be set prior to running.

These following three variables SHOULD be set to any existing directory where the user has read/write permission. If they are not set, the CURRENT working directory (where Calnic C was started) is used as the default!

• CNC_CAT Catalog output directory
• CNC_DATA Directory Calnic C looks for input data files
• CNC_SPECOUT Default directory to write Calnic C output files

  The following variable MUST be changed so that the CALNICC_BASE/bin is included in the path. Placing it in your shell startup script (e.g. $\sim$/.cshrc) is recommended

• PATH Command search path

The Bourne Shell ($CALNICC_BASE/bin/calnicc) may be edited, but this is not recommended. If it is decided to edit the file, please bear the following in mind:

The following variables MUST not be changed by the user:

• IDL_STARTUP IDL startup script
• CALNICC_BASE Calnic C's installation base directory
• CNC_CAL Calibration directory
• CNC_SW Calnic C software directory
• CNC_LIB Library directory
  

  The following variable MAY be changed provided that the CALNICC_BASE/bin is somewhere in the path:

• IDL_PATH The IDL search path
