EXAMPLE: imscript.csh

This csh script is used to make a continuum image from a calibrated data. The script involves several Miriad tasks, such as, invert, mfclean, restor, cgdisp, imstat. Here is the details:

#!/bin/csh -f
# an example of script to produce MFS continuum image
# from calibrated SMA data.
# invert, clean, restor and cgdisp
