20190701 DX 4D alignment

Alignment

10:30 Set M2 and M3 to November 2019 positions
  • see glint on 4D
  • Move M2 to see Full Pupil
  • 1100 images

11:30 Pupil it too high and left.
  • Use delta M3, M2 numbers from 20190208
  • Nicely placed in center of 4D image
  • M2 Final position:
    m2_final.jpg
  • M3 final position:
    m3_final.jpg

12:10 Hand over to Alessandro to collect pictures of 4D beams.

1:20 Collect new hexapod reconstuctor
  • /local/aomeas/adsec_calib/hexapod/20190702_202105/
  • print, hexalign(/apply)
  • 225 nm rms

1:30 can not plot on ADSEC IDL terminal
  • change elevation limit to 30 and restart
  • OK now

21:10 flatten with 200
  • /local/aomeas/adsec_calib/flat/20190702_211038/flattening_result.sav
  • 311 nm rms
  • Next flattening with 200 modes is worse. Must measure new reconstructor

  • 20190702_211546
  • May be too much error along outter edge. A lot of bumps

21:30 Flat with fewer modes
