20040417 report

CW Inclinometry OK.


Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20040322  90  cw      00:08     -0.8     -0.6   -0.5      80 )
    20040417  90  cw      22:47       ?        ?      ?        ?

This is the first successful run taken since a failure on 11 April, and the first with the new ENVIRO-ment taks operating. My old method of retrieving humidity and antenna leg temperatures from the WEATHER task is no longer viable - and those parameters will remain blank until I learn how to access the new data base. The last leg temperature data taken in the old way are shown here.

All data channels of the inclinometry data look OK. The resulting CW model is compared below with the current one - that taken on 22 Mar :

  • The result shows no significant changes in the intervening 4 weeks. (Phew !).
  • 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 19 Apr 2004.
  • The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.30", 0.31", 0.35") cf (0.49", 0.18", 0.31") previously.
  • Records of the symmetry and strain gauge data have been updated; all looks fine.
