Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20021005  90  cw      02:15      0.0      0.3    0.7     100 )
    20030101  90  cw      10:06      6.2      7.2    8.0      30

The resulting model is compared with the previous model of 05 Oct :.

The new model itself can be seen here.

• The acquired azimuths were those demanded, and there are is no sign of the problems reported earlier in the week due to the antenna/carousel not reaching their demanded positions.
• The formal differences in (F1,F2,F3) are described by the rms scatters of (0.56", 0.64", 0.53") c.f. (0.45", 0.26", 0.59") previously; so a little worse, but maybe not unexpected given the difference in the temperatures of the structures and the long interval between the datasets.

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

• The model was installed at ~10:00 on 02 Jan 2003. Although somewhat of a 'warm' model, it is at least up-to-date, and should be superseded without huge changes by the next 'colder' model we get.
