Open Loop Data
==============

  Data Collection
  ---------------

     We have completed quick-look processing on the following MEX RSR open
loop data at Stanford:

     As Gene Goltz noted, this was not flagged as a Radio Science pass; but
all signs indicated that good radio science data could be obtained, so he
went for it.  The result may be the best set of solar conjunction data we
have acquired so far.

     There are spurs at several frequencies around the carrier; but their
relative amplitude is low.  All channels appear to be independent (that is,
there is no evidence that the same signal is being received on two channels
as was the case on days 241-243).  Sample histograms show no evidence of
clipping, though the S-LCP channel is very close.  And tuning is excellent;
the carrier is at almost 1000 Hz all the way through the four hours.  Signals
have drifted and been offset from the center frequency in recent passes; but
these data appear to have been acquired with new predicts.

     X-LCP started about an hour later than the others, presumably because of
contention for RSR's at Madrid.
