Miscellaneous
=============

     This is the first report since HEA6011A.TXT.

     The spacecraft entered safe mode on 2006/007 and was in the process of
recovering when the last of these data were collected (2006/011).

  Anomalies
  ---------

     The X-band carrier is about 150 Hz below the center of the passband on
2006/004, suggesting use of an old orbit or set of RSR tuning predicts.  The
same offset is present on 2006/006.  This may simply be the result of reduced
staffing over the holiday period.  These offsets should not affect science
processing of the data.

     The spacecraft entered safe mode on 2006/007; reports from RMDCT indicate
that it was out of safe mode on day 008, but the occultation data suggest
otherwise.  In the first OCI on 008 the X-band carrier starts at 600 Hz above
the center of the passband and has drifted almost to the edge by ingress;
there is no S-band signal.  For the second OCI there are two signals within
the X-Band passband; but the stronger has only 12 dB SNR, so these may be
images of the real carrier.  The drift is similar to the first occultation,
and there is no S-Band signal.

     On day 010 the X-band carrier starts 200 Hz above the center frequency
drifts to about 650 above the center at OCI.  These data and the data from
the first occultation on 008 may be one-way.  There was no S-Band signal on
day 010 and no RSR data were collected.

     On day 011 the X-band carrier stays near the center of the passband and
the occultation appears to be nominal, suggesting two-way data.  But there
was no S-Band signal, so the second RSR was not used.
