  Data Collection

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

     With the exceptions noted below, these appear to be good data.  Note that
three occultations were completely lost and one may be significantly
compromised because the integrity of the data samples is in question.

  Anomalies
  ---------

     On 2006/035 the DSS 63 X-Band data (orbit 2654) have weak signals
scattered across the spectrum; the raw power in the samples is about 30 dB
below the level that is expected.  On S-Band there is only noise.  There
appears to be nothing in either recording that can be used by science.
Danny Kahan postulated a couple possible reasons for the absence of signals,
but nothing can be confirmed.

     On 2006/036 the DSS-15 data (orbit 2658) have no signal.  According to
Danny Kahan, "the antenna was stowed until a problem calibrating the
transmitter could be resolved" (DR #G106505).  Presumably the RSR ran while
the antenna was pointed to zenith.

     On 2006/037 a pass (probably orbit 2661) was switched to DSS 65 because
the DSS 63 LNA was "red."  The rescheduling information reached RSSG too late
to rewrite the RSR script.  No data were played back to JPL.

     On 2006/039 the X-Band I and Q samples from DSS 65 (orbit 2668) have
distinctly different distributions.  There is no obvious explanation, and the
data collected two days earlier and one day later (presumably using the same
equipment) show no such anomalous features.
