The central bearing load was adjusted during the afternoon, and a report by Tomas Chlylek is available here. In summary, "the load distribution between the central bearing and the rollers has been kept at 85%/15% of the total antenna weight".

All data channels of the inclinometry data look OK. The resulting model is compared below with the current one - that taken on 04 Mar :

• The result shows significant changes - no surprise following the CBLA.
• The new CW model was merged with the new (CW-CCW) template to create a new hybrid track model, which was installed at HST 18:30 on 10 Mar 2004.
• Records of the symmetry and strain gauge data have been updated; all looks fine.

Allsky Pointing followed :
33 data were recorded with SCUBA :

The elevation performance is essentially nominal, while azimuth residuals are a strong function of elevation : a sure sign of the usual change in the azimuth encoder zero-point (IA). The data were run through TPOINT: IA has changed by 22" and small changes to the other terms were allowed. With the new model the performance ought to look like this :

or this

- with rms's in (daz,del) of (0.8", 1.4"); TPOINT 'RMS on sky' = 1.4".
