20050724 report

CW inclinometry

Reports for 2005                     Pointing Home Page


Inclinometry was then done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20050713  88  cw      15:00      7.0      8.5    9.5      50 )
    20050724  88  cw      09:00      2.0      2.8    3.5      80

All inclinometry and temperature data channels look OK. 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 13 Jul is shown below:

  • There are track-segment-correlated structures throughout, but reaching only 1" in amplitude.
  • The differences in (F1,F2,F3) are described by rms scatters of (0.37", 0.37", 0.40") c.f. (0.84", 0.35", 0.43") previously.
  • The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 09:40 on 26 Jul 2005.
  • The symmetry (defined here) and wheel loads remain at post-CB-load-adjustment levels.
