Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %
  ( 20040417  90  cw      22:47       ?        ?      ?        ? )
    20040430  90  cw      22:19      3.2      2.7    2.4      90

All data channels of the inclinometry data look OK. The resulting CW model is compared below with the current one - that taken on 17 Apr :

• There are some odd systematic changes, although of small amplitude.
• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 12:15 on 04 May 2004.
• The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.40", 0.30", 0.35") cf (0.30", 0.31", 0.35") previously.
• Records of the symmetry and strain gauge data have been updated; all looks fine.
