Plan for the day

- work on NCPA correction

Summary

- started on NCPA, already some success

- determinted image scale N30-camera

- bug in GEIRS for HW/DET windowing

Details

All times are UT
Files are luci2.20150121.NNNN.fits

- LUCI rotator/cabling test done: ok

- Subwin read-out:
entering the correct commands is not activating HW/DET windowing
-> min exp time is NOT changed
-> Richard is looking for the issue: bug in present SW, new version has to be installed (tomorrow)

Data analysis for both HeI & Br_gam

NCPA testing & calibration with DM (multiple aberrations,
turbulence, maximum coeffs to be applied and being stable)
