20041230 report

CW Inclinometry OK


Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20041215  90  cw      15:07      8.6      9.5    9.9      25 )
    20041230  90  cw      23:59       

All data channels look OK; the difference between the model resulting from the new data and the current one (of 15 Dec) is shown below:

  • The differences in (F1,F2,F3) in the latter case are described by rms scatters of (0.28", 0.13", 0.28") c.f. (0.68", 0.26", 0.25") previously.
  • The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 10:15 on 31 December 2004.
  • The symmetry (defined here) is as large as it has been in 2-3 years. However, the explanation cannot be underloading of the front wheels, since the wheel loads - as judged from strain gauge No.2 only - are OK.
