# DESCR.: Create dispersion masks for a list of arclamp exposure in a given directory
#         and a given input dispersion mask. Save output masks and logfile in
#         convenient directory structure. 
# USAGE:  ldmask_loop.sh <parameter_file>, where <paramter_file> 
#         sets variables mainpath=, night=, userparfile=, parfile=,
#         input_dispersion_mask=, arclinefile=, arcs=, tracedirname=, traces=,
#         masterbias=, 
#         (for example parameter file see ./ldmask_loop.params)

# 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
