UT 20150127 LUCI2 AO Nighttime Commissioning

Observer LUCI-Team: JHeidt, WSeifert, APramskiy, DThompson (LBTO)
Observer AO-Team: SEsposito, GAgapito, EPinna, APuglisi
Telescope Operator: Sallenson
LBTO Support: TSargent

Plan for the night

Will be clouded out so closed-dome stuff:
- understand the ROTangle dependence of NCPA
- test a new reconstructor with larger modulation

Summary

- Clouded out all night

- Several performance tests of NCPA

- Tests to reduce vibrations

Preparations

- Retroreflector was installed

Details

All times are UT
Files are luci2.20150127.NNNN.fits

00:53 Sunset, overcast, Hum = 80%, Temp=1.4deg, Wind 10 m/s

- MCE disconnect: PS1 exchanged with spare @ 26.01. 19:00 UT, (last error was 25.01. 22:30 UT)
run FWs periodically before starting other tests
-> no discoonect in the following hours

- AO preset send tests -> successful

- Check best focus / NCPA @ ROTangle = 270deg

- Performance test of NCPA @ ROTangle = 150, 205 and 270 deg

- Performance test of NCPA vs. seeing at 3 λ / D and 4 λ / D modulation @ WFS

- Check NCPA vs. elevation -> very stable at ele > 40deg

#0010 nice PSF wink

- Tests NCPA higher than Z11 (up to Z21)

- Tests damping/rejecting vibration using digital filters
