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

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

     We have completed quick-look processing on the following MEX RSR open
loop 100 kHz bistatic radar data at Stanford:

     All data appear to be of good quality.  Results of quick-look processing
of the 25 kHz data from this experiment were reported in HEA9111A.TXT; those
data also appeared to be good.  X-RCP and X-LCP echoes have power densities
several times larger than the noise baseline and at least an order of
magnitude larger than the noise fluctuations with 10 seconds of averaging.
The noise appears to be well-behaved.  Since the observations were conducted
near the Brewster angle (approximately 60 deg from vertical incidence), this
experiment is a good candidate for deriving X-Band dielectric constants along
the specular track from about (30N, 8E) to (40N, 10E) even though MEX was near
apocenter and Earth-Mars range was over 2.1 AU.


  Anomalies
  ---------

     No S-RCP bistatic radar data were collected because the maser lost gain
following a 'cryogenic glitch.'  This means there will be no S-Band dielectric
constant estimates and no comparison of values at 3.6 and 13 cm wavelengths.
Word yesterday from DSS 63 was that the maser was performing normally again as
we prepare for the next experiment on day 2009/115.
