Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20030412  90  cw      02:30      0.2      0.3    0.4      75 )
    20030526  90  cw      10:59      5.0      6.2    6.8      70

All data channels were OK. The resulting CW model is compared with previous CW model -- the one taken on Mar 12 below :

They are merged with the recent (CW-CCW) average to create a new hybrid track model.

• The differences in (F1,F2,F3) for the CW models are described by the rms scatters of (0.57", 0.53", 0.49") c.f. (0.45", 0.57", 0.41") previously.

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

• The hybrid model was installed at 14:15 HST on 27 May 2003.
