# This script creates mc sequences and datasets for a psf, observation mode 
# and zenith range chosen by the user.
#
# variables, that have to be set by the user:
# - dir        directory, where the mc sequence and dataset files are stored 
#               be careful: don't move the sequence files afterwards, as the 
#               paths are stored in the datasetfiles
# - mars       directory, where your Mars version is stored
#               only needed, if you want to create a rf-root-file for the 
#               energy estimation 
# - sourcefile directory, where your Mars version is stored
#               only needed, if you want to create a rf-root-file for the 
#               energy estimation 
#               be careful, you also have to set the mars path in sourcefile
# - zdmin      minimum zenith distance
# - zdmax      maximum zenith distance
# - psf        psf 
#               at the moment mc with psf 14 and 20 is available
# - modes      observation mode
#               the explanation for the modes can be found in 
#                /montecarlo/rawfiles/README.txt
# - numruns    num of runs, that are in the sequence file, which are used for
#              training (SequencesOn in $mcdataset)
#
# If you want to create a rf-root-file for the energy estimation, you have to 
# comment out the 'exit' before the last lines of the script.
