20040313 report

CW Inclinometry OK.


Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20040310  90  cw      15:30      0.6      1.3    1.6      80 )
    20040313  90  cw      11:50      1.5      2.1    2.7     100

All data channels of the inclinometry data look OK. The resulting model is compared below with the current one - that taken on 10 Mar :

  • The result shows no significant changes - only small F3 systematics at the start indicating that either this run or that on the 10th was started too early - before the inclinometer in the cabin had settled.
  • The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.28", 0.16", 0.33"); small enough that no update to the track model seemed justified.
  • Records of the symmetry and strain gauge data have been updated; all looks fine.
