Restoring operation

Start at 11.30 AM AZ time (in the following we will use UT TIME)

Modified the file /lbt/tcs/2012C/aos/.../SXOffload... to disable offload of high order modes to M1 to prevente M1 panic in daytime. Remember to revert for the nights. Restart AOS after that

Spots are found soon on the IRTC camera with M2 global offset [2.6, 0.13, 4.5, 317, 574,0]

M3 is in the standard leftback bent gregorian position

Acqpupil mode has to be changed to the single circle fit instead of 4, Alfio takes care of it.

Best cube rotation position found at 240.33

Hard working on the concrete pier of the telescope to install PEPSI platform: big oscillation present.

Test of KL_v9 bin1 reconstructor to be sure that we are still ok

Ho fatto un po' di casino a salvare questi dati, l'immagine IRTC è senza senso (no filtro) ma il modalplot è significativo e sembra che non ci siano problemi. Il loop a 400modi con il disturbo sta chiuso normalmente con il disturbo da 0.8".

Save a flat 20120530_400modi.

KL_v10 calibration

La KL_V10 è fatta con slaving degli attuatori dell'anello interno del secondario. Per dettagli sentire AR e FQP

Si comincia a fare l'acquisizione della IM per la KL_v10, più per identificare eventuali problemi che per avere buone calibrazioni visto il lavoro martellante sul telescopio.

Si mette comunque tutto al meglio: HBS on, treehouse fans sx e dx off, elevation brakes disengaged. Non serve a molto.

Si vorrebbe provare i ricostruttori ma c'è l'handover. Nella fretta si prendono 3 misure inutili con il rec a 10 modi. In realtà il 20120530_222710 è stato brevemente provato con successo ma non ci sono dati. Domani li prendiamo

Due immaginette che Carmelo ha voluto assolutamente mettere relative alla IM 20120530_222434:

How to switch off treehouse fan and open the vent doors

1. Open the box in the treehouse with 5 eurocent

2. Turn off the fan rotating to the left the labeled switch (up-right)

3. Move to off the labeled switch in the box (low). The window opens

4. Move the switch back to on (the fan starts and a beep rings)

5. Push the reset the button from the panel OUTSIDE of the treehouse. The beep stops

We tried to test different elevation brakes/stow pin combinations.

At first glance, the best operating condition seems to be with elevation on and all the brakes off. (thanks to John Little)
