20020920 report
Further CW Inclinometry, OK
Inclinometry was done as follows :
Datasets El Dirn HST mean leg temperatures Humidity
start start middle end %
( 20020817 90 cw 03:01 3.6 3.6 3.6 65
20020824 90 cw 21:39 8.5 8.2 7.7 90
20020904 90 cw 21:06 7.5 6.9 6.6 80
20020905 90 cw 01:41 6.0 5.5 5.3 65 )
20020920 90 cw 10:02 4.5 6.0 7.3 50
The temperature data from the fixed TMU inclinometer went awry early on,
so the new data are not temperature-corrected.
The resulting model is compared with the previous model (of the 17th) below :
-
There are no signs of 'spikes'. 'End effects' may be the result of
the absent temperature corrections.
-
The formal differences in
(F1,F2,F3)
are described by the rms scatters of
(0.32", 0.30", 0.64").
-
Updates have been made to the plots of
symmetry
and
strain gauge data.
All looks OK.
-
The model of the 17th is left in place, since
- the changes seen are small
- the data are imperfect (no temperature corrections made)
- the temperature prevailing for on the 17th is (still) closer to normal
observing temperatures than these
- the interpretation still holds that the data of the 17th are free from
spikes.
