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

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

     In the data beginning at 2006/025-23:51:00 (orbit 2619) there is a weak
square wave amplitude modulation on the X-Band carrier.  Its amplitude is
approximately +/-0.1 dB and its period is about 45 seconds.

     In the data beginning at 2006/030-04:43:00 (orbit 2634) the S-Band
analog to digital converter is completely saturated - to the point where
the samples may not be useful for science. The spectrum is severely distorted.
Since this is the only DSS 14 occultation in the set, it is impossible to
draw firm conclusions; but the attenuator setting for this observation
was 9 dB LOWER than the attenuator setting for the DSS 15 observation two
days later.

     In the data beginning at 2006/032-03:47 (orbit 2641) there is a 0.2 dB
drop in the carrier level approximately every 3 minutes.  These are brief
and the final "glitch" is 5-6 minutes before ingress, so there should be
little imapct on the science.

     Otherwise, these data appear to be of good quality.
