The file, fitskeywds.dat, contains entries for FITS keywords used
by
Calnic C. Since it is likely that different data sets will use
different
keyword values for specifying the same item of interest to Calnic C,
flexibility is needed. For example, some FITS files might use the
keyword
OPT_ELEM to specify the optical component used for an
observation. Other
FITS files on the other hand, might use the keyword FILTER to
specify
the same optical component! It is possible to edit the value of the
keywords used by Calnic C (see Figure 5.4) while
running
NICMOSlook. Use the button 
to change these
values.
From within IDL, simply type nlk_edit_fits_keywords at the
prompt.
This will pop-up the parameter editor. The changes take effect
immediately
after hitting the 
button on the editor pop-up. See
section C.3 for the default values.
