Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity

    20041003  90  cw      10:17      5.5      6.7    7.1      26 )
    20041022  90  cw      02:02      7.0      6.6    6.5      60

The resulting CW model is compared below with the current one - that taken on 19 Sep :

• The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.38", 0.24", 0.30").
• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 15:30 on 22 October 2004.
• Records of the symmetry and strain gauge data have been updated; all looks fine.
