[daip] Convolving from Jy/px to Jy/beam

[Amy Mioduszewski]

Hi Juan-Carlos,

The help file is a bit confusing, it looks like if OPCODE='GAUS' and the input 
image is in Jy/pixel then FACTOR=1 will convert the units to Jy/beam.  If 
FACTOR=0 then it will be unscaled.  Is you convolving beam several times your 
pixel size?
