Inclinometry has been done as follows :

All channels of the new data were OK. The resulting model is compared with previous one taken on 12 Oct below :

• There are changes in the track model terms, similar to those seen most recently and the inverse of those the time before that. The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.47", 0.23", 0.24") c.f. (0.46", 0.27", 0.36") previously.

• This time the new (CW) model was merged with the recent (CW-CCW) average to create a new hybrid track model, which was installed at HST 11:30 on 27 Oct 2003.

• The data have nonetheless been used to update the plots of symmetry and strain gauge data. All seems OK.
