# Controlled initial-value ray tracing in model SALT
# followed by plotting of the computed rays
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# This history file calculates rays shot in the x1-x3 plane
# and plots the computed rays.
# This history file is designed to be run from another history file
# (see e.g. 'sal-test.h'), which runs 'srp.for' to generate source
# coordinates 'sal-src.tmp' and then executes this history file
# for the source.
