Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20050106  90  cw      22:00     -1.5     -1.6   -1.6      60      
    20050107  90 ccw      02:00     -1.6     -1.7   -1.6      45 )
    20050118  90  cw      22:09      5.5      5.1    4.9      80
    20050119  90 ccw      00:56      4.9      4.7    4.6      80

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 06 Jan is shown below:

There is a slight problem with the initial F3 (elevation) data, indicative of a too-early start to the data collection. This persists through the following plots, but is small enough to ignore.

The differences in (F1,F2,F3) are described by rms scatters of (0.37", 0.74", 0.68") c.f. (0.38", 0.89", 0.75") previously.

The difference between the new CW and CCW models is shown below:

It looks similar to the previous CW-CCW difference - of 06/07 January.

The difference between this (CW-CCW) difference and that of the 06/07 Jan CW-CCW difference is shown below :

The differences in (F1,F2,F3) are described by rms scatters of (0.48", 0.28", 0.39").

i.e. the January 06/07 and 18/19 CW/CCW pairs are sufficiently similar to justify using them to create a 2005 CW-CCW template.

• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 11:55 on 19 January 2005.
• The symmetry (defined here) continues to rise. As last time, however, the explanation cannot be underloading of the front wheels, since the wheel loads - as judged from strain gauge No.2 only - are OK, even if lighter than last time.
