Inclinometry was done as follows :

    Datasets  El Dirn     HST     mean leg temperatures   Humidity
                          start     start   middle   end       %

    20030228  90  cw      10:30       -        -      -        -

The tilt data from the X-axis of the TMU inclinometer was no good for most of the run of the 28th - see plot, so a repeat was requested. (NTM discoverd the FILTER switch setting to be ON instead of OFF on 03 Mar, which may explain the odd behaviour).

The data of 01 Mar were fine until v.near the end when the temperature data from the TMU inclinometer went occasionally wild. These errors were massaged away before temperature corrections were applied to the tilt readings. The resulting model is compared with previous model -- the one taken on 09 Feb :

The data are only in minor ways different from those of the 09^th and are used to create a new track model. The most significant feature is a 3" glitch at azimuth 154; origin unknown. I have not attempted to eliminate it from the data.

• The differences in (F1,F2,F3) are described by the rms scatters of (0.32", 0.45", 0.28") c.f. (0.25", 0.40", 0.54") previously.

• Updates have been made to the plots of symmetry and strain gauge data. All looks OK.

• The model was installed at 10:00 HST on 03 Mar 2003.
