Inclinometry was done as follows:

The datafile was given an HST-derived name. Data is recorded from the 3 active inclinometers only: there is no strain gauge data, for instance.

The data are good, and of truly normal TY amplitude:

• The differences between the (CW) model derived from these new data and a) (left below) that in place in January 2006, and b) (right below) that created on the 23rd are shown below:
  

  The plot on the left shows rather minimal changes in F3, while those on the right suggest that any pointing done with the model of the 23rd could suffer errors of several arcseconds in elevation at many azimuths.

  A hybrid track model was created using the (CW-CCW) profiles from 2005, and was installed at HST 20:15 on 30 August 2006.

  (20060831 HST) CW-CCW
  CCW data with this same configuration was acquired at the end of the same night. The CW-CCW differences from the new data are shown here:

  

  The difference between CW and CCW runs remains very stable: see the difference between this measure and the 2005 template. This validates the way the hybrid track model was created last night (using the 2005 CW-CCW template), and the data obtained in the last 12 hours form the basis of the 2006 CW-CCW template, cw-ccw2006.dat.
