20061010 report

CW/CCW inclinometry : fine, track model updated


Inclinometry was done as follows:

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20061003  89  cw     ~02:15     9.3       9.2    9.1      --
    20061003  89 ccw     ~04:30     9.1       8.9    8.7      -- ) 
    20061010  89  cw     ~03:10     6.9       6.9    7.0
    20061010  89 ccw     ~05:30     7.0       7.1    7.2

Data is recorded from the 3 active inclinometers only: there is no strain gauge data, for instance.

  • The differences between the (CW) model derived from these new data and the previous model of 03 Oct are shown below :

    • rms differences in (F1,F2,F3) are (0.30", 0.36", 0.29") c.f. (0.31", 0.42", 0.19") last time.

    The CW-CCW differences from the new data are shown here:

    The F1 difference between CW and CCW runs seems, again, of somewhat larger amplitude than previously and before that . . .

    A hybrid track model was created using just the new CW-CCW profile and was installed at HST 09:25 on 10 Oct 2006.
