WARNING.  Uses results of BC2 processing of the North that were copied
into UGAP7.  Make sure the current version of the Northern files is in
UGAP7 before using these files.

calib stolen from ../bc1 and not from ../bothcal

parfit stolen from ../bc2

CALIB is used to get southlist.01
   (GETSAME knows where the SAME files are)

FIELD is used to get southfield.01

Then use PARFIT to get soucoef and iterate.

NSFIT fits splines to the observations and leaves a sampling of the
blue and red data in SAMPLE.NS, puts the nodes in NSNODES.B/.R and
prepares the final version of the node file NSEDIT.B/.R for user
modification.

NSFIT XX where XX is the iteration number from PARFIT to use.

NSFINAL takes NSEDIT.B/.R and makes NSLUT.B/.R

When done, copy SOUCOEF.XX and NSLUT.B/.R into UGAP7 before attempting
to calibrate the catalog.
