COSMOS includes programs to (1) calculate and adjust the mapping between the
CCD focal plane and the science plane (wavelength vs slit coordinate) (2)
reduce data, (3) provide quick-look capabilities, as well as some utility
programs. All programs have a specified set of input parameters which may be
entered on the command line. If more than one input parameter is required, they
are denoted by flags and may be entered in any order. Alternately, if no
parameters are specified, the program will prompt for them. Most programs have
an associated parameter file, whose name is program.par
. The parameters in
each parameter file are listed with each program. Parameter files may be edited
with the utility program editpar. Parameter files must be located in the
directory specified by the environment variable COSMOS_PAR_DIR.
IRAF routines which are part of the COSMOS packages follow IRAF conventions for
input parameters and parameter files. However, although each of the routines
with names irafroutine8 does have a parameter file, one should instead use the
IRAF routine epar to edit the parameter file for the standard IRAF
program irafroutine.
