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

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

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

     The data from 2005/001 and 2005/003 are of good quality and should yield
good profiles after analysis.

  Anomalies
  ---------

     There is no usable signal in the data from 2004/366.  A weak X-band
signal lurks on the lower edge of the 2 kHz passband, but never moves closer
to the center than about 80 Hz.  It disappears at about the time an
occultation would be expected.  There is no signal at all in the S-band
data.  It appears that the tuning for both receivers was in error; exactly
what went wrong is not clear.

     The X-band carrier in the other observations is accompanied by spurs at
frequencies suggesting weak modulation by power line harmonics.  These are
common at SNR near 50 dB/Hz and higher; the spurs on 2005/001 at DSS 63 (when
the signal was strongest) are the most pronounced.

     The presence of one additional record in the X-band data from 2005/003
as compared with S-band in the same observation may complicate downstream
merging of the resulting files.
