Colleagues,

Attached is a spreadsheet with the results of the rfcal runs of Sept 12
and 14.  For the 103 cavities measured in the NL, the momentum nominally
is 1.002 times the momentum measured with the procedure.  For the 84
cavities measured in the SL, the momentum nominally is 1.04 times the
momentum measured with the procedure.  Looking at just the 9/12 data,
the ratios were 1.04 and 1.08 respectively.  Measuring more cavities
brought the ratios closer to the lem fudge factors of 1.006 and 1.018
respectively.

There are another 89 cavities that could be measured in the NL and 113
in the SL.  202 * 1.5 minutes ~ five hours plus overhead, call it one
shift.  I think it worthwhile, YMMV.
