Pointing

The cause of the pointing variations are still being investigated. The hydrostatic bearings of the telescope were tested. No change ($<<10 \mu m$) in the height of the hydraulic pads was detected, while the movement corresponding to the observed variations in the pointing would be 0.19 mm.

The pointing variations are very stable and we have been operating with the same pointing model for a long time with no complaints, and we hope that we will be able to improve the pointing by applying corrections to the current pointing software.
