[daip] [Fwd: scimg question]

Sorry, please disregard my question (below), I mistakenly assumed that 
SCIMG would make image cubes when run on spectral line data, that is not 
the case. It makes images, not image cubes.
So does SCIMG use the first channel only?
Thanks,
Hanno.

Hello, I have a question about scimg.
The scimg helpfile says that one should first transform the spectral
line data into a "continuum" data set using split, uvcop, etc.
However, if you run scimg on your line data you seem to end up with a
datacube which you could then average using sumim.
Is this ok?
In this way one could avoid bandwidth smearing.
I must add that I probably have anough s/n per channel for selfcal (it
is P-band VLA data centered on SgrA).
Thanks,
Hanno.
