#
# Sample C-Shell script for fv 2.6
#
# This script will open 2 sample files (available online and distributed
# with the fv executables) and displays their contents in several forms...
# header keyword list, a curve, and an image. It uses the XPA program
# xpaset to control fv. XPA is not distributed with fv, but can be
# obtained from the SAO/HEAD R&D group at
# http://hea-www.harvard.edu/RD/xpa/
# You will need to build the TCL version as well as the executables.
#
# USAGE:
#
# After starting fv, executed this script file on the command line:
# ./XPAScript.csh
#
########################################################################
# Set an environment variable here which points to the fits files
# to be opened. This is just to make it easier to specify files
# later.
setenv FitsDir ftp://heasarc.gsfc.nasa.gov/software/ftools/release/other/pdw
#
# Open 2 sample files
#
xpaset -p fv open $FitsDir/ngc1316r.fit $FitsDir/rate.fit
#
# Select one of the files and open a header window of extension #1
#
xpaset -p fv select rate.fit
xpaset -p fv display header 1
#
# Plot a curve of Time vs Rate in POW and alter the graph's appearance
#
xpaset -p fv display curve 1 time rate
xpaset -p fv pow bounds 770 -30 1070 300
