Horizon activities

JZ starts to work on ?? up to 8:00.

Zenith activities

After telescope is back to Zenith we perform several task in parallel:

1. Reconnect cables and pipes of the LgswUnitDx that was left incomplete in August (MB)
2. Recheck the alignment of the CalUnitSystemSx using the alignment mask (DP). We found a 0.3deg tilt of the beam in the vertical direction, towards the table plane. We don't know if it is due to a misalignment of M3 or the dichroic optics.
3. Service the BeamCorrectorSX gears on the SX side (SR): mots are found inside the LBC box. Optics are cleaned and system is reinstalled.
4. Supply power and ethernet on the LgswRack1 (JZ)

16:00 we have to handover the telescope.

We try to start the LgswUnitDx, we have a problem with the PCD: or the amplifier is switched off or it has a wrong IP, we can't reach it.

New PatCam angles:

Beam	Angle
Blue	3.0
Yellow	-172.0
Red	180.0

New Pupil motors position for IS:

Beam	X	Y
Blue	462	425
Yellow	282	404
Red	394	260

Check of SX CalUnit alignment

There was a tilt visible in up down direction of approximately 0.25 deg. Tertiary was move to compensate. Final position:

However, even with this values the angle was not removed as M3 was not pistoned.
