JZ starts to work on ?? up to 8:00.
After telescope is back to Zenith we perform several task in parallel:
- Reconnect cables and pipes of the LgswUnitDx that was left incomplete in August (MB)
- 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.
- Service the BeamCorrectorSX gears on the SX side (SR): mots are found inside the LBC box. Optics are cleaned and system is reinstalled.
- 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
New Pupil motors position for IS:
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:
|X ||Y ||Z ||RX ||RY ||RZ ||M3Tip ||M3Tilt ||Piston ||RZ |
|3.05 ||-0.45 ||1.9 ||-227 ||-77.3 ||0 ||-1315.97 ||291.009 ||0 ||0 |
However, even with this values the angle was not removed as M3 was not pistoned.
