Users should subtract 1 second to obtain the correct times. Time tags between 1999-273T02:50:00 and 1999-273T04:05:00 are advanced by 2 seconds; users should subtract 2 seconds to obtain the correct time. Time tags in the corresponding ODFs have been corrected. Time tags on (one-way) data between 02:05:00 and 02:50:00 are also wrong, but the size of the error is not known at this time. It has not been corrected in ODFs released as of this date. A corrected ODF has been promised. -------------------------------------------------------------------------- From flemoine@ares.gsfc.nasa.gov Tue Nov 2 05:34 PST 1999 Received: from ares.gsfc.nasa.gov (ares.gsfc.nasa.gov [128.183.106.250]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id FAA00905 for ; Tue, 2 Nov 1999 05:34:18 -0800 (PST) Message-Id: <199911021334.FAA00905@magellan.stanford.edu> Received: by ares.gsfc.nasa.gov; Tue, 2 Nov 1999 13:34:33 GMT Date: Tue, 2 Nov 1999 13:34:33 GMT From: Frank Lemoine To: rsimpson@magellan.stanford.edu, trish@rodan.jpl.nasa.gov Subject: unexplained signatures in residuals Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=X-roman8 Content-Length: 243 Status: RO Trish- was there a tracking station anomaly or a s/c maneuver (trim maneuver) between 990929 2111 to 2359, and maybe early into the next day? The residuals at that time seem quite unreasonable. The station tracking is station 25.

It is only DSS 25 that appears affected though from 990929 2100 to 990930 to about 0347. Frank > > Hello, Frank, > > Do the data have a sort of sawtooth appearance?
