# This script is: 
# - writing rc-files with different sets of cuts 
#   the set of cuts can be steered with the variables 
#   $par3step, $par3numminus, $par3num and
#   $par1step, $par1numminus, $par1num
#     par*step     step width for changing the parameter * 
#                  (suggested value: 0.005)
#     par*numminus number of steps going to smaller values of the parameter * 
#                  (starting value in your ganymed.rc file) 
#     par*num      number of steps for changing the parameter * 
#     par3: Cut1.Param3 from the ganymed.rc file 
#     par1: Cut1.Param1 from the ganymed.rc file 
# - writing a condor dag file for spectrum study
#   With submitting this dag file with condor_submit_dag to condor from your
#   Mars directroy you are running ganymed and sponde for all different rc 
#   files. The condor dag man is taking care of the order of the jobs, 
#   i.e. that sponde is started just when ganymed has been finished.
# 
# To start several spondes please set the arrays $spondes.
# It is also possible to start new spondes without rerunning ganymed and/or 
# the other spondes. To do so, please set the variables $doganymed and 
# $spondedones accordingly
#
# Remark: You have to submit the condor dag file from your Mars directory.
# 
# For more detailed information read the comments directly before
# each variable.
