Technical Observing: 28 November 2012 UT
Observer: DMiller, JGuerra (LBTO)Telescope Operator: DHuerta (LBTO)

Summary
- Original Cow Active Optics works (converged at the beginning of the night)
- Fallback from Sext to new Cow when not enough spots are found by Sext
- New Cow collimates proplerly
- Sextractor Act Optis converge with beginning of the night collimation
- iif.async for left and right should be set to 0 if monocular (iif_init.pro)
Details
00:01 Open Chamber 00:30 Change links to GCS.20121127.V2.7.3.3 and to directory GCS.newWFS 01:00 David send ACTIVE preset. OK. A lot of coma, but collimating. Using original Cow because UseSextract false in LUCI_L.cfg (from testing). 01:10 Change to UseSextract true (and set rm_flat to false). Now new Cow is being used. Sext is finding 0 spots. Error running sex, .nnw file not found. Torsten copy the file and Sext now used. 01:20 GCS and IDL sext output is exactly the same. 01:25 Cancel preset. David clears C00 and Active Optics on Primary and Secondary so we can do a beginning of the night collimation with Sext. 01:30 Active Preset fails: Guiding Sext could not find a file. The new GCS put in a "left" in a file name where it shouldn't. Stop and start GCSL and it works for the first preset. Torsten will fix and make new patch. 01:34 Restarted GCS and Preset successful. Collimate from beginning of the night with Sext. OK 01:43 Patched GCS. David stop and start GCSL. 1st preset successful. 2nd preset successful. Problem fixes. 01:56 Confirmed that IRAF:rangebal works. We should be ready to collect a pointing and collimation model. Confirmed that the M1 and M2 values in the wfsc image header. 02:10 Test my IDL pre 02:21:01 Shell ripped. Active Optics continues and collimate to ~150 nm WFE for the sensed modes. Z12-Z22 sensed ~700 nm, but are not being sent. Not sure the scale factors are correct. See wfsc image 111.Sextractor collecting data.
02:30 - 04:30 JC collects sext data The sexstractor active optics was running during the acquisitions of various fields at different conditions; faint star, vignetting, large aberration, astigmatism, bright background.

with bad seeing and vignetting the active optics drops the rms to 480.
- bad seeing and vignetting:
high background and it is not getting the star
