#
# The sampler values correspond to N_on N_off, respectively (note that sampler calls JSampler),
# where:
# N_on   =  number of time slices to read;
# N_off  =  number of time slices to skip.
#
# The sampler option works as follows.
# It will
# read -on average- N_on  consecutive time slices and  
# skip -on average- N_off time slices
# modulo the number of time slices in the file.
#
# The larger N_on, the faster the reading, because this reduces the random accesses 
# of the data taking file to pick up a next time slice.
# The smaller N_off, the less time slices are skipped.
# So, N_on = 0 guarantees that all time slices are sampled.
# Note that if the number of time slices to be produced is small, then too small a value of N_off
# could create a bias because only the first time slices of the data taking file are then sampled.
