UT 20120205 AO/PISCES technical night

Observer: DMiller (tucson), JCarlos (LBTO)
Telescope Operator: DHuerta (LBTO)
Telescope Support: JUrban(LBTO)
Instrument Support: DOfficer (LBTO)

Summary

-Test of the new preset modes to close the loop and apply offsets during the close loop. Several presets were sent with a good success in most all of them. The last preset, early in the morning failed during the autogain procedure, this was due to a bad seeing ~1.3" and the high background

-Check performances of the close loop.

-Check PSF quality in Pisces, the images showed a poor psf, this has to be investigated tomorrow (morning).

Details

First half was TCS Testing with TCS Build 2012B. TCS was reverted to BP14 for the second half.

Clouds passing. good seeing ~0.8" till the last hour where the seeing was about 1.3".

9:10 Opened chamber

Target in the ND holder plate.

We had a few minutes to check the ND holder plate using a diffuse source. The source is a piece of paper that cover the ND holder with a small hole in the center illuminated by a torch. A few images were taken and this test will be done tomorrow with more time to center and to fix the position for the ND holder plate.

Filter positions.

Images taken with 20 seconds exposure used to identify the filters posiitons. The table below shows the new positions..

long exposure images.

During the close dome we took a serie of images with light ON/OFF. The filter used was J. The test to check any possible vignetting in the optical path of Pisces.

AO loop performances.

With the problems due to the bas quality of the Pisces images we used teh elab tool to check the performances. Below is a table of the perfomarnce and a modal plot.

The quality of the loop close could be seen in the CCD47, where diffraction images could be seeing. Unfortunally the images were not saved.

After talking with the Arcetri Team, the note in the elab are not true, this is a wrong information from the elab. An issue track was activated: n#3939
