[daip] VLBACALA and ACSCL

[R. Craig Walker]

If you run ACSCL after APCAL, it undoes the APCAL calibration, since it is
trying to make the calibrated autocorrelation coefficients unity in the
designated channel range.  Therefore, it must be run before APCAL.  But it
also must be run after ACCOR and after the derivation of the bandpass. 
Therefore it must be run between the two major components of VLBACALA.  I
suggest that VLBACALA be broken into two procs, one for ACCOR and one for
APCAL.  In fact, my latest HYB.001 has such procs defined.

I would appreciate having those two split for other reasons.  Mainly, I
find I often have to iterate and experiment to get APCAL with opacity
fitting to work.  I'd rather have ACCOR behind me at the point and not
have to either keep redoing it, or have to keep setting up APCAL and CLCAL
without the help of the procs.

Cheers,

Craig
