Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20051205  89  cw      06:52      4.3      4.2    4.3      90 ) 
    20051208  89  cw      03:48      2.4      2.4    2.4     100

The zero-points when at (az,el) = (10:00:00, 88:47:00) are now all ~zero. All inclinometry and temperature data channels look; Ch13 - the #1 strain gauge - is still not functional.

The difference between the CW model resulting from these new data and the previous one of 05 Dec is shown below:

There are obvious track-segment features, but at least of small amplitude.

• The differences are v.small and (F1,F2,F3) are described by rms scatters of (0.34", 0.51", 0.63") c.f. (0.43", 0.28", 0.66") previously.

• The new CW model was merged with the (CW-CCW) template to create a hybrid track model, which was installed at HST 12:00 on 15 December 2005.

• The symmetry (defined here) remains fine. although the wheel loads have increased by 20% or so.
