I have not examined the code in detail but the help file makes it
pretty clear that it is a total correction.  If not, then SN 3 should
be virtually zero on all antennas.  An SNPLT using different GRCH for
different INVER would let you check on this.  The 3 SN's will be
similar (assuming that a reasonable 1st model arose) is they are
total.  Otherwise, the first will be much larger than the 2nd which
will be much larger than the 3rd.
