Inclinometry was then done as follows :
Datasets El Dirn HST mean leg temperatures Humidity
start start middle end %
( 20050713 88 cw 15:00 7.0 8.5 9.5 50 )
20050724 88 cw 09:00 2.0 2.8 3.5 80
All inclinometry and temperature data channels look OK.
Ch13 - the #1 strain gauge - is still not functional.
The difference between the CW model resulting from these new data and the
previous one of 13 Jul is shown below:

-
There are track-segment-correlated structures throughout, but
reaching only 1" in amplitude.
-
The differences in
(F1,F2,F3)
are described by rms scatters of
(0.37", 0.37", 0.40")
c.f.
(0.84", 0.35", 0.43")
previously.
-
The new CW model was merged with the
(CW-CCW) template
to create a
new hybrid track model,
which was installed at HST 09:40 on 26 Jul 2005.
-
The
symmetry
(defined here)
and wheel loads remain at
post-CB-load-adjustment levels.
