[daip] Problems averaging channels.

[Craig Walker]

I would like to get a POSSM output data file without as many channels as 
I'm getting now by averaging channels.  I have tried two methods, both 
with problems.

First AVSPC:
default avspc
   ind 3; getn 71
   outn=inn; outcl='avspc'; outs=ins; outd=ind
   docalib=1; gainuse=maxtab('CL'); flagver=maxtab('FG')
   doacor=1; channel=3; avoption='subs'
   smooth=1,0

That takes in a 2150 vis file and turns it into a 24 vis file with only 
the autocorrelations from one station.

Setting DOACOR=-1 left an empty file.

SPECR:

default specr
   ind 3; getn 71
   outn=inn; outcl='specr'; outs=ins; outd=ind
   npoints=1024

Seems to give a good file, but with the sort order blank which causes 
POSSM a fit.  I can either SORT or change the header, but that's a bit 
awkward.  I don't think it changed the vis records so I'm not sure why 
the sort order changed.

This is all on noatak at the aoc, disk 3.

Cheers,

Craig
