Dear SWARM Data Aficionado,

   The attached table lists the fringe rates, at one minute intervals, for the six baselines 
which were active during our SWARM test track taken on Nov. 21.   The table gives the UT time, 
the source name, and the fringe rate on each baseline, in Hz.

   I've processed the "fixed" version of the SWARM data, to produce plots like the ones Mark 
showed at our meeting.   To produce the plots, I passband calibrated the data with the BL Lac scans, 
then did phase-only gain calibration with BL Lac and MWC 349 and finally did amplitude gain 
calibration using BL Lac with an assumed flux of 1.0 (which is why my amplitude scale does not agree 
with Mark's). I did not need to adjust the frequency axis in any way to get the lines to overlap. 
I've attached the plots to this missive.   They are quite similar to Mark's, but I think my 
plots show a bit less disagreement between the two correlators in the shape of the line.   
My plots only show a really significant line shape difference on baseline 6-7. I see about 
the same noise difference that Mark saw.
