Can you please >confirm that the problem is gone. The bad DSS 63 spurs reported for the 273/274 pass had been cleared up by the 275/276 pass. So there were only two really bad days. 63 may have the distinction, however, of the worst spurs outside of those two days. In the plots for 20455e I can see spurs at +/-50, 60, 180, and 300 Hz. The picture is similar both before 273 and since 276. This is not intended to be a new alarm, just an observation. -------------------------------------------------------------------------- From aseel@airmail.fltops.jpl.nasa.gov Wed Oct 8 04:58:59 2003 Date: Tue, 7 Oct 2003 19:25:01 GMT From: aseel anabtawi To: aseel.anabtawi@jpl.nasa.gov, chinsan@magellan.stanford.edu, data@magellan.stanford.edu, joe@neptune.stanford.edu, kusza@magellan.stanford.edu, rsimpson@magellan.stanford.edu DSS: 63 RSR: RSR1A Subchannel: 1 Orbit Number: 20467 Occultation Sense: e SOE: mm316a.07.tsoe Ground Mode: 1 Uplink Station: -- Sampling Rate: 2K Bit Resolution: 16 Begin Record: 2003/279-20:42:00 End Record: 2003/279-20:56:00 DSS: 63 RSR: RSR1A Subchannel: 1 Orbit Number: 20467 Occultation Sense: i SOE: mm316a.07.tsoe Ground Mode: 1 Uplink Station: -- Sampling Rate: 2K Bit Resolution: 16 Begin Record: 2003/279-22:08:00 End Record: 2003/279-22:22:00 DSS: 63 RSR: RSR1A Subchannel: 1 Orbit Number: 20468 Occultation Sense: e SOE: mm316a.07.tsoe Ground Mode: 1 Uplink Station: -- Sampling Rate: 2K Bit Resolution: 16 Begin Record: 2003/279-22:39:00 End Record: 2003/279-22:53:00 DSS: 63 RSR: RSR1A Subchannel: 1 Orbit Number: 20468 Occultation Sense: i SOE: mm316a.07.tsoe Ground Mode: 1 Uplink Station: -- Sampling Rate: 2K Bit Resolution: 16 Begin Record: 2003/280-00:06:00 End Record: 2003/280-00:20:00 DSS: 63 RSR: RSR1A Subchannel: 1 Orbit Number: 20469 Occultation Sense: e SOE: mm316a.07.tsoe Ground Mode: 1 Uplink Station: -- Sampling Rate: 2K Bit Resolution: 16 Begin Record: 2003/280-00:37:00 End Record: 2003/280-00:51:00 -------------------------------------------------------------------------- From dale.k.howell@lmco.com Tue Nov 4 09:47:38 2003 Received: from mailgw3a.lmco.com (mailgw3a.lmco.com [192.35.35.7]) by magellan.stanford.edu (8.11.6/8.11.6) with ESMTP id hA4HlbQ17498 for ; Tue, 4 Nov 2003 09:47:37 -0800 (PST) Received: from emss02g01.ems.lmco.com ([166.29.2.54]) by mailgw3a.lmco.com (8.11.6p2/8.11.6) with ESMTP id hA4HlLZ09601; Tue, 4 Nov 2003 12:47:23 -0500 (EST) Received: from CONVERSION-DAEMON.lmco.com by lmco.com (PMDF V6.1-1X6 #30760) id <0HNU00E019BVR6@lmco.com>; Tue, 04 Nov 2003 10:45:32 -0700 (MST) Received: from EMSS02I00.us.lmco.com ([166.29.2.48]) by lmco.com (PMDF V6.1-1X6 #30760) with ESMTP id <0HNU00IKS9BVDS@lmco.com>; Tue, 04 Nov 2003 10:45:31 -0700 (MST) Received: from EMSS02M15.us.lmco.com ([160.205.32.138]) by EMSS02I00.us.lmco.com with Microsoft SMTPSVC(5.0.2195.2966); Tue, 04 Nov 2003 10:45:30 -0700 Date: Tue, 04 Nov 2003 10:45:21 -0700 From: "Howell, Dale K" Subject: MGS Fuel and Mass Update 03/267 to 03/279 To: "Dick Simpson (E-mail)" , "Elsa Jensen (E-mail)" , "Frank Lemoine (E-mail)" , "Gene Brower (E-mail)" , "Grant Faris (E-mail)" , kds , Mike Malin , "Pauline Hwang (E-mail)" , "Tom Thorpe (E-mail)" , "Darren Baird (E-mail)" , "David Jefferson (E-mail)" , "Eric J.
