Thermal cycling primary mirrors while running FPIA all night.
At the end of the night we also managed to take some superfocus data.


We had to run lbckill/lbcstart at the beginning of the night.

01:14 Preset to WT10_377
  • lbcrangebal
  • after the first dofpia we run
  • dofpia, redlimit=10, bluelimit=10

03:05 change exptime to 32sec in dofpia
  • dofpia, /X2, redlimit=10, bluelimit=10

05:38 start cooling the mirrors

05:45 at around 05:40 the dofpia software exited because it reached 99 iterations which is the maximum number (!!)
Red is analyzing,  Blue is analyzing
Maximum number of iterations exceeded       99 without convergence.
Sending last Sph3 (Z11) correction for RED channel      -371.365
  • restarting dofpia
  • dimm seeing 0.7''

07:26 Gracefully exiting fpia - manually clear active optics on both sides , clearing c00

07:27 start dofpia again
  • dofpia, /X2, redlimit=10, bluelimit=10

08:20 exit dofpia and change field because this one is getting too low

08:21 Slewing to ACT0383
  • dofpia, /X2, redlimit=10, bluelimit=10

10:42 start warming up the mirror

10:51 Gracefully exiting fpia - manually clear active optics and c00 on DX
  • the red side is really struggling - it gave -14000 Z4 and in the next iteration +14000
  • start dofpia again

11:11 clear active optics on both sides and c00 on both side

11:41 clear active optics and c00 on DX side

12:44 Gracefully exiting fpia and start the superfocus tests

12:46 RB_rV_superfoc7.ob

12:53 dofpia (took 2 iterations)

12:57 RB_rV_superfoc7_pa180.ob

13:03 dofpia (took 8 iterations)
  • timestamp:13:09:60 - lbcb.20120106.130923.fits- pupil fitting algorithm problem with the blue image

13:15 RB_rV_superfoc_coarse180.ob

13:20 dofpia (took 1 iteration)

13:24 RB_rV_superfoc_coarse.ob

13:27 dofpia (took 2 iteration)
  • too bright - the background is 5000counts and we stop

13:31 end of night
