# AUTHOR: C. Herenz
# DATE: June 2012
# DESCR.: Create a flat-field (2D flat-field spectrum) to be used on science frame
#         - using the conventional p3d flatfielding method, i.e. transmission array 
#         and dispersion correction both from twilight flat
# USAGE:  cflatf.sh <parameter_file>, where <paramter_file> 
#         sets variables mainpath=, night=, userparfile=, parfile=,
#         - this file uses the conventional flat fielding (just twilight flat) -
#         TODO: write list of parameters here

# test if argument is provided is provided and file is existent
if [ -z "${1}" ] || [ ! -f ${1} ]; then
    # .. if not, quit gracefully!
    echo "Supply parameter file as argument!"
    exit 0
