I only ask because the pass from 00 0813 1422 to 1722 seems well behaved - but the pass from roughly 1800 to 1920 goes haywire. Were they doing funky off nominal pointing exercises around that time - either with the HGA or the spacecraft? (we use the quaternions so that should take care of things like that - but I was just wondering) -Frank -------------------------------------------------------------------------- From Pasquale.B.Esposito@jpl.nasa.gov Tue Sep 26 14:23 PDT 2000 Received: from eis-msg-012.jpl.nasa.gov (eis-msg-012.jpl.nasa.gov [137.78.160.40]) by magellan.stanford.edu (8.9.3/8.9.3) with ESMTP id OAA19739 for ; Tue, 26 Sep 2000 14:23:54 -0700 (PDT) Received: from [137.78.144.173] (esposito-mac.jpl.nasa.gov [137.78.144.173]) by eis-msg-012.jpl.nasa.gov (8.9.3/8.9.3) with ESMTP id OAA18033; Tue, 26 Sep 2000 14:24:37 -0700 (PDT) Mime-Version: 1.0 X-Sender: pesposit@pop.jpl.nasa.gov Message-Id: Date: Tue, 26 Sep 2000 14:24:35 -0700 To: dsmith@tharsis.gsfc.nasa.gov, flemoine@ares.gsfc.nasa.gov, rsimpson@magellan.stanford.edu From: "Pasquale B.

The SOLVE page showed that the AMDs were all between 15-19 mm/s. Also, the fit did not have the signature that we would have expected had an AMD been missing during that time period. For the sake of completeness, I looked closely at some corrupted data that occurred on August 13 to ensure that it was not caused by a missing AMD. This data had to be removed from our solution, and Eric reminded me that an ISA was written on this data, and a solar flare was identified as the root cause. Since the fit for this batch of orbits appears normal (i.e. no signature) and since the AMDs are spaced at the usual 7-hour intervals, it is clear to me that we are NOT missing any AMDs on August 13. If you need any more information, I will be glad to give it to you.
