The 19 to 20 seconds is interesting because there is a mystery 0.056 Hz mode (approx. 18 sec) which has been screwing up the TES data. They have written an MCR requesting that solar array auto-tracking be disabled temporarily so that they can see if that's what is causing their problems. The leading theory is that the SAM panel (the broken one) is introducing this mode as the array auto-tracks. They may eventually request that the arrays only be moved a couple of times an orbit which would benefit you as well. ...

This requests "a strategy of tracking the solar arrays in discrete steps (or dwells) of approximately TBD minutes in duration or TBD degrees in rotation as MGS orbits during the remainder of the Mission." Reasons for the change are that "solar array tracking induces noise in the TES data. This source of noise must be mitigated. The induced noise in the TES from the solar array tracking completely compromises the limb, polar, and atmospheric data." The problem is that the background noise level in TES data increases by a factor of 10 when the solar arrays are tracking. This is particularly bothersome during times when the instrument is pointed at low intensity targets. These include space (which should be almost totally dark), the limb (mostly dark, depending how close to the surface), and polar regions (cold, and thus dark). John explained that the solar arrays have been identified as the culprit through a process of elimination and some recent tests. Curiously, the problem wasn't noticed until fairly recently. All through Aerobraking, TES seemed to be working OK. But some time before HGA deployment, the increased noise level became apparent. There was a test in the last couple weeks during which the SA gimbals were stopped, and the TES problem went away. I conclude, and I think John agrees, that the evidence does not point toward a sensor or vibration problem. More likely, there is some sort of coupling between SA gimbal activity/signals and signals in the TES hardware. I'll leave it up to TES and S/C engineers to figure this one out. I don't see any impact from MCR #397 except that sudden bursts of SA activity probably should be kept out of occultation windows -- at least until we have confirmation there is no impact on our own observations. I wouldn't be surprised if other instruments also had the same concerns. and our gravity investigators. We should also follow this because of the possible spinoffs to our own concerns about 5 Hz artifacts from the HGA gimbals.

DUring SPO-2, one regime apparently was used near periapsis, and another for ANS (trish decoded all this information for SPO and sent out an email on this subject in January'99) During SPO-1, according to the quaternions, the solar array attitude was fixed. The continous gimbaling of the solar arrays may be the cause of the TES instrument noise and since continuous gimbaling only has been going on since (apparently?) the end of GCO.
