## update Pyxis if you haven't done so since 05 Feb 2015.
## Also ensure that you have lwimager installed
# run as $ pyxis msname image[options] 
# options can be: cellsize,npix,gain,wprojplanes,column/data, etc 
# to make a per N channel image add im.IMAGE_CHANNELIZE=N
# Find the MSs at jake:~makhathini/ratt/imaging
