# quantile grid generator
# generate grid patterns for spectra modeled by any two parameters
# this is very similar to grid.pl, but instead of evaluating
# values along the grid lines, it maps out 2-d uniformly

# Refer to

# and references therein

#
# input
# Run the program without option for basic options or see below.
# For the model names and their parameters, refer Sherpa or
# xspec manual. As for the parameter name, one can simply use numbers
# (e.g. A.1 or B.1 instead of A.nh or B.PhoIndx), and the parameter
# names can be found in sherpa (load a model and type "show").
#
# output
# The result will be dumped into the screen in RDB format.
# One can save it by piping.
# e.g.) grid.pl .... > result.rdb
# For RDB format, refer
# http://hea-www.harvard.edu/MST/simul/software/docs/rdb.html
# Basically, it is an ASCII text table file where
# each field is separated by .
# The file will contains 2+n columns where n is the number of "frac"
# you request.
# First two columns are the two parameter values, and the rest will
# be the quantiles (Ex% but not Qx).
#
# limitation
# potentially many, but the accuracy of grid is limited by
# the energy scale of rmf and arf files. Need to be re-visited at
# some point.
