When doing a pointing run using the point procedure file and acquire command, results are logged in /usr2/log/sx.log and they can be plotted to keep track of progress. Here's an example of what can be done. Copy and paste this into a file on the pfcs machine, then 'source' it.

egrep '(xoffset)' /usr2/log/sx.log > xoff.txt
egrep '(tsys)' /usr2/log/sx.log > tsys.txt
gnuplot <<EOF
