Hmmm, OK, so when I initially looked at the SY table in SNPLT using multiple plot types, I did notice a few places where the counts rose very quickly, or dropped very suddenly, so I used TYSMO with the defaults set (and inext='sy').  It seems, like you said, that I did not do much.  I did apparently apply the flag table though by using the default and that deleted many of the jumps in counts as far as I can tell.  
The messages I am getting are for every antenna.  Here is just a little bit of the print out:

The 0.634346 does not change, it is always there in the messages.  
When I compare antennas 2 and 12, I do not see anything particularly interesting in SNPLT.  However, I did notice that the antenna 12L power plots do all sit at 0 at this timerange, which is strange because that timerange is not flagged for antenna 12 LL.  So that is a bit concerning.  I checked the full timerange and I see the same throughout.  I have not use antenna 12 as a refant, so I am not sure why it looks that way in these plots. I also looked at antenna 12 in tvflg and it looks normal for rr and ll in that timerange...I am not sure what is going on there.
If I can skip this part, I will.  I have checked for amplitude and phase jumps already in the data using LISTR with optype='gain'.  I have also done some basic TVFLG'ing (checking amplitude, amplitude difference, phase, and phase difference for LL and RR).  I am under the impression that TYSMO is used to to fix systematic problems(?).    So, perhaps it is fine to skip it, since I have looked for problems in TVFLG and LISTR?
