Summary

LDG

02:30 Open Chanber

03:00 Preset to BS9152

03:24 pupil wobble with pupil_collect

• /home/dlmiller/data/20130621/pupil_wobble
• ~1 pixel radius

03:35 field_collect

• /home/dlmiller/data/20130621/initial
• Had put last night's LFBG values on M2, Tip=+3, Tilt=-12
• Nearly 0 focal plane tilt

04:26 Change M2 position from tip=+3, tile=-12

• Delta Tip=-15, Tilt=-7, (final Tip=-12, Tilt=-19)
• Manual 0.970 0.613 0 -17.840 186.579

04:29 field_collect

• /home/dlmiller/data/20130621/tip-15_tilt-7
• disable AdSec LUT application during three off-axis acquisitions
• Some focal plane tilt but about the same binodal (at the noise level)

05:30 Installed new M2 position in config files

• Created /home/telescope/TCS/Configuration/PSF/SXSMMODSCollimation.20130621.dat
• Created /home/telescope/TCS/Configuration/PCS/SX_Gregorian.20130621.ptmod
• Edited /home/telescope/TCS/Configuration/PCS/PCSInstrument.conf
• Created /home/telescope/TCS/Configuration/PCS/PCSInstrument.20130621.conf

05:35 Steve restarted PCS and reinitialized PSF. All Good!

05:40 Pupil_subap_collect moving in Y. Some poorish, variable seeing now.

06:30 preset to South. Better

07:01 pupil_subap_collect moving in Y from -10 to -340" steps -10

• /home/dlmiller/data/20130621/pupil_subap_y

09:02 pupil_subap_collect moving in Y from -90 to -340" steps -10, X=270

• /home/dlmiller/data/20130621/pupil_subap_x
