20020824 report

Further CW Inclinometry


Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20020817  90  cw      03:01      3.6      3.6    3.6      65 )
    20020824  90  cw      21:39      8.5      8.2    7.7      90

The temperature data from the fixed TMU inclinometer are OK, so the new data are temperature-corrected in the usual way. The resulting model is compared with the previous model (of the 17th) below :

  • There are weak (1") signs of 'spikes' - perhaps as a result of the high-ish temperatures.

  • The formal differences in (F1,F2,F3) are described by the rms scatters of (0.54", 0.23", 0.50") c.f. (0.43", 0.28", 0.51") previously, so from this characteristic the data look useable.

  • Updates have been made to the plots of symmetry and strain gauge data. The new strain measures show solid loading !

  • The model of the 17th was left in place.
