Running the Program

 Before attempting to run Calnic C make sure that all environment variables (section 5.3) and system config files (section 2.6.1) are set to desired values. To run, simply type the following at the UNIX prompt:

• calnicc direct.fits grism.fits
  (where direct.fits and grism.fits are the fits files of the direct and grism images respectively)
  or
• calnicc -f im_list (where im_list is an ascii file containing a direct and grism FITS file pair, plus the name of an optional object list, per line. This list should be in the same format as what is produced by the companion program NICMOSlook (See section E)).

The first method demonstrates how to call Calnic C with a single direct/grism FITS file pair. The second method shows how to process a series of direct/grism FITS file pairs that are stored in an input file.
Refer to the following section for a more detailed description of the input Calnic C requires.
