Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity

    20040828  90  cw      10:38      6.8      7.7    8.5      30

All data channels of the inclinometry data look OK. The resulting CW model is compared below with the current one - that taken on 13 Aug (and not reported here):

• The -4" spike in F1 at az=90.7 has been removed by interpolation.
• The differences in (F1,F2,F3) between these two CW models are described by the rms scatters of (0.37", 0.24", 0.29").
• The new CW model was merged with the (CW-CCW) template to create a new hybrid track model, which was installed at HST 10:00 on 30 August 2004.
• Records of the symmetry and strain gauge data have been updated; all looks fine.
