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

     This is the first report since HEA8267A.TXT.


Erratum
=======

     The previous report (HEA8267A.TXT) mentioned that the spacecraft carrier
disappeared during occultation measurements scheduled for about 22:00 on day
257.  Danny Kahan discovered that the ground transmitter failed for 9 minutes
one round trip light time before the occultation.  With no uplink, the
spacecraft signal would have drifted off to its rest frequency, outside the
passband being recorded.  The failure was documented in DR G108821.


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

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

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

DOY DSS        RSR        BAND RSR CH KSPS BT  REC   RECS      RSR      MAX
          START    STOP         ID         RS  LEN          FILE NAME   SNR
--- --- -------- -------- ---- --- -- ---- -- ----- ----- ------------ -----
267  15 21:23:00 21:43:00 X/XR   4  1    2 16  8260  1201 8267212A.RSR  48.9

     There was no S-Band downlink for this pass.

     The X-Band signal looks good, but telemetry modulation was on, reducing
the carrier power by about 10 dB compared with its expected level with no
modulation.
