Introduction
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 paramater file are listed with each
program. Parameter files may be edited with the utility program editpar. Unless a full
path is specified, parameter files are searched for in the following
places (1) the current directory, (2) ~/cospar (3) $COSMOS_HOME/cospar.
At the Baade Telescope, a ~/cospar directory will be created for you
when you
follow the instructions for setting up on either llama or burro.
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.
