> Detailed Description :
> Hi,
> Since 2012-03-22 night the IQ degradation has become more recurring.
> It happends in a random way and in many different positions.
> With or without guiding and/or with or without doing active optics.
>
> As far as I know, the only thing that changed duirng this week is that guideprobe was enable on March 22th 2012.
>
> The following are some examples of 2 different OBs
>
>
> This was without guiding and AO loop was closed only in OB 639814 and 639838

> Thanks Carlos for putting this ticket and giving it 'Critical' priority, to which I full agree. I reassign to Optics for the time being, and include Pietro just in case.
>
> We have had to repeat of order 5-6 hours worth of OBs in the nights March 23 and March 25, due to IQ degradation.
>
> It is difficult to make remote analysis. For one, the external IQ is quite good which makes any defocus become very apparent.
>
> A few questions, trying to isolate the problem:
>
> - Is the guide probe by any chance physically vignetting part of the FOV, in particular the edges where auxiliary chips are? (should not be the case, but better ask). Is the real position corresponding to that indicated in the GUI?
> - Is the ADC deployed and in SIM? Should not be.
> - Has the noise in the IA images increased strongly? See 44375, 41464.
> - Is the magnitude restriction of IA stars working correctly? Have a look at ocmia.fits images in DETDATA at times before strong IA degradation: are the donuts unsaturated and noise-free?
> - IA corrections are apparently converging, so I assume that correcitons are being sent to the telescope? Please doublecheck by sending a few aberrations via vstaberwriteGUI (or something like that) in twilight. Do standard star aquisition which brings system into shape. Then apply the aberrations and check what the OCAM system sends back in a new aquisition.
> - Are the passive forces controlling the mirrors still being sent at preset, and not every 30s?
> - Do we by any chance have a new focal plane tilt? I see that chip 96 at one edge is typically most out of focus. But this is a remote analysis, and I do not know how this would happen anyway.
> - Is M2 'jumping' spontaneously?
>
> Any further clues most welcome. I will be at Gemini Observatory the next 3 days, so hopefully Thomas Szeifert has some bright ideas? Thomas comes up on Thursday I think, and me on Friday.

> The root cause for the image degradation is the curved focal field of the telescope (principally at wavelength > 550 nm) imaged by a flat detector plane. A little bit of defocus will cause about the degradation reported in the ticket.
>
> According to the reports it only occurs in open loop observations and only with the red r,i,z,H_alpha filters.
>
> It would occur more often when the seeing is very good. The seeing was quit good in the last weeks.
>
> When ever you detect image degradation you can stop the auto fetch and force an IA.START = "T".
>
> I think that we will have to repeat >>10 of the observations for this reason.
> 2012-03-26 20:31:48 smieske
> Can you please backup all ocmia.fits images from March22nd onwards in DETDATA into some subdirectory. Just to make sure they are not erased. And please, send me a 'ls -ltr ocmia*fits' of DETDATA as it is currently, so we keep the information of timestamp vs. image number.

> Hi Steffen,
> -The guideprobe is not vignetting
> -ADC is OUT of Focal Plane and not in SIM
> -The magnitude restriction is working OK. Although in some images I saw some noisy images the previous days, the examples that I paste were always OK.
> -I haven't seen M2 jumping.
>
> Hi Thomas,
> The degradation also happends with AO loop closed as it is shown in the KIDS OB pasted before.
>
> On the night the 23/03/2012 I enabled a couple of times the IA START keyword to T in order to perform an AO correction (Vphas concatenation) but even with this the degradation persisted.

> As discussed with Carlos, the amount of OBs with IQ degradation is much higher than normal, and occurs in both open and closed loop. Therefore our interpretation is that there is something else happening, than just the typical occasional defocus. And hence we assign this as technical downtime until clarified. Does everything look normal at the phyiscal telescope/instrument interface? Is the AG/IA integration time OK (20-30s)?

> HI:During this night I started with KIDS OBs and I got much ellipticity. and also image degradation
> First of all always the automatic mode failed to acquire guiding and when doing it manually, the guide stars availables were not coincident with trhe red circles that shows well known catalogue guide stars. Then after every exposure the guiding was lost. Another strange behavior is related with IA stars. IA stars also were always selected manually and most of the time were stars far away from catalogue points (red circles) While the observation was running I could clearly see that the IA stars in the patch started to drift ending at a very corner of the square patch.
> As a result of this images on science rtd were elongated most of the time.
> Please consider this in your analysis.

> 2-3 times I experienced that these parameters were not loaded correctly and the pointing became suddenly poor. The reason was that, if I remember well, the parameters are loaded only when the ws software (trkws) is initialized. If one LCU is not ready to receive the parameters (e.g. because it is switched off or is rebooting) in that moment, maybe afterward that axis will work without any pointing model. If you are in such conditions the automatic selection of guide stars will certainly fail and the stars will drift more than usual.

> If that is the case, the most radical way to recover should be:
> 1) reboot the 3 LCUs,
> 2) check the parameters on the 3 LCUs (I think they should be all 0)
> 3) send INIT - ONLINE to trkws
> 4) check the pointing model parameters again on the 3 LCUs.

> Anyway I would ask TCS staff in Paranal to perform this check.

> But checking the behavior of these OBs the degradation its kind of random, in the sense that with AO sometimes had this problem sometimes not, and without AO same thing, also these programs are executed very close to the meridian ( half an hour after until one hour) and low airmass, but the IQ degradation get better with a higher airmass than 1.2, and i do remember that the image quality of the VST and the focus had some problems or lets say was not very good in this positions during the commissioning even after the intervention. and the magnitud of the problem was different if you use a differents filters, maybe this is the problem. So i think that a good test could be try to executed this programs below airmass 1.2 or from airmass 1.2 abnd also do the AO correction more often, now is after 5 Obs or more, maybe it will better after 3 Obs.
