PDS_VERSION = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 1997-09-19 NOTE = "MGS RST Instrument Health Report HEA7262A.TXT" END_OBJECT = TEXT END Miscellaneous ============= The NERT Cache was misbehaving last evening. The first few queries were rejected; a phone call to DSOT was never returned. Eventually the Engineering and Monitor queries were accepted, but less than 5 hours of engineering data and only the first ~18 hours of monitor data were received. There were no error messages -- as though the data simply never made it to the NERT Cache.

He reports: We have been looking at MGS tracking data since MOI. Everything looks fine until 09/16 00:00 (4.5 hours about after the MOLA pass and before the delta-v to start aerobraking, which was at 09/16 16:58?) ... then we see large biases in the Doppler data (39 to 46 km/s) ... obviously something is not right here. Did something change on the ODF's for that day?
