20090727 report

CW/CCW inclinometry updated

27 July 2009


This inclinometry run was carried out on 26th July.

The new data are recorded from the 3 active inclinometers and one of the two strain gauge channels. The LT trace, which showed strange behaviour during the previous inclinometry run now shows no problems.


  • The differences between the (CW) model derived from this run and the previous run on 18th July are shown below.

  • The resulting rms scatters in the differences in (F1,F2,F3) are (0.38", 0.29", 0.35") compared to (0.35", 0.48", 0.25") last time.

  • The CW-CCW profile is normal, and is used to generate a hybrid track model which was installed on the 20th July at 11:00.

  • The strain gauge analysis suggest the loasing on the wheels continues to hold steady. (see strain gauge data).
