Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20030129  90  cw      16:12      7.9      8.9    9.1      30 )   
    20030209  90  cw      10:15      3.0      4.0    5.0      15

The temperature data from the TMU inclinometer was no good, so no temperature corrections are not applied to the tilt readings. The resulting model is compared with previous model -- the one taken immediately after the central bearing load adjustment on Jan 29 :

The data are only in minor ways different from those of the 29^th and are used to create a new track model.

• The differences in (F1,F2,F3) are described by the rms scatters of (0.25", 0.40", 0.54") c.f. (0.34", 0.24", 0.37") previously.

• Updates have been made to the plots of symmetry and strain gauge data. All looks OK.

• The model was installed at 21:30 on 09 Feb 2003.
