Once analyzed with a Gaussian fitting of constant width (19, 12 arcseconds) and in the AzEl (trueHorizon) coordinate system we obtain these curves:

{{attachment:OnOff_Mars_20111018_60_2mm.jpg| JitterOnOff at 2mm | width=400}} {{attachment:OnOff_Mars_20111018_60_1mm.jpg| JitterOnOff at 1mm | width=400}}

Here we show in Nasmyth coordinates the instantaneous calibrated maps obtained during the sequence On Off where the Off is still in the array. The Off position is 25 arcsec. away in Az and 25 in El. Each subscan is 10 seconds. There are 18 subscans. Analysis is on progress to assess the pointing jitter from these data.

Scan 60 in 20111018.
