[daip] QUACK

[Jim Ulvestad]

Yes, I know I can do that.  This particular observation has about
20 scans, so it would take only a few minutes.  I'm just looking
for a simpler tool, that I also could use for an observation with
200 scans!  It's possible that it's not feasible to do with QUACK,
but I thought I'd ask.
