Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20050130  90  cw      10:21      1.7      2.7    3.7      70 )
    20050206  90  cw      04:15      2.0      2.1    2.1     100

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 30 Jan is shown below:

• There are noticeable, but small (+-1") humps, esp. in the delta(F1) plot, and a 2" artifact in F1 at 345.

• The differences in (F1,F2,F3) are described by rms scatters of (0.54", 0.37", 0.28") c.f. (0.46", 0.35", 0.37") previously.

• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 09:35 on 10 February 2005.
• The symmetry (defined here) remains essentially unchanged. The wheel loads - as judged from strain gauge No.2 only - are OK.
