PALM-3000 Analysis of current alignment
• Alignment Req.: 1/20 pixel RMS, Goal:1/40 pixel RMS– Is this the right requirement?
• Pupil size is what we expect to 0.2% • Pupil A/B ratio: 1.0170 (target) 1.016 ± 0.001(measured)

PALM-3000 HOWFS - Tasks Left
• Order new optics, install, re-align• Test in white light• Testing of new CCD50 readout modes
• Format• Noise
• Internal compliance / flexure testing and validation• Integration into the testbed• Test pupil shift necessary for ‘s63’ mode• Testing closed loop AO with HODM!
