Following the odd results with the tiltable inclinometer over the last few days, a run with the 'fixed' TMU inclinometer was made :

The model resulting from the data of the 27th is compared below with the model from the 17th :

• The datasets seem very similar (the earlier data has the spike at azimuth ~135) and the new model will be accepted.

• The formal differences in (F1,F2,F3) between these data are described by the rms scatters of (0.24", 0.17", 0.24"), cf (0.28", 0.38", 0.32") previously. The similarity is as striking as any pair of data at any time in the past, and seems to reflect great stability in the track over this 10day period. Similar stats for the difference between the new model and that of the 25th are (0.58", 0.55", 0.58"). The use of this previous model would not have reduced pointing accuracy by any more than 2" anywhere.

• Updates to the plots of symmetry and strain gauge data look normal, and show no confirmation of the low wheel loading seen in February.

• The new model was installed at ~16:30 HST 28 Mar 2002.
