GC_NIC
This task produces the raw science FITS files for further analysis. Both
the science data as well as the support schedule and engineering telemetry
are formatted as standard FITS (Flexible Image Transport Standard) files.
For NICMOS multiaccum data this task reverses the order of the frames in
the exposure. Thus the first exposure in the file is the last frame which
was read out of the instrument.

Context
Inputs
Most components of the "EDT" set (.PKX, (.DQX), .TRX, .DGX, .DVX, .DCX,
and the .ULX) are used in this process, and most of that information winds
up in one of the two FITS files produced. All input files should reside
in the user's working directory (the .DQX file is optional). Note that the
ipppssoot may be wild-carded.
Outputs:
This task produces the ipppssoot_RAW.FITS and ipppssoot_SPT.FITS file.
The first contains a primary header with observation-specific information
followed by exposure or frame-specific header keywords and the binary
raw science data for that frame. The second contains a primary header
with the support schedule keywords (.DGX) followed by frame-specific
telemetry keywords (.DVX, .DCX) and the binary internal header (.ULX).
Constraints
The input files must exist in the user's default directory and
the output files will be created there as well.
Examples
$ GC_NIC N20Q0102T
This command creates N20Q0102T_SPT.FITS and N20Q0102T_RAW.FITS file for
the above observation.
$ GC_NIC N20Q01*
This command creates FITS files for each observation in the current
working directory whose name begins with N20Q01
