20190703 DX 4D elevation -vs- flat tests (for Guido)

Setup

16:20 UT get telescope
  • yesterday's postions of M2, M3 are close. A bit of hand alignment
  • print, hexalign(/apply)

17:01 flat /local/aomeas/adsec_calib/flat/20190702_231412/flattening_result.sav
  • 634 modes
  • 88 nm rms
  • Once got a bump at 376. Hight force and a bump seen in 4D. ~370 modes

17:17 Start flat -vs- elevation measurements
  • apply flat /local/aomeas/adsec_calib/flat/20190702_231412/flattening_result.sav

  • apply_45.sav
  • 430 nmm rms
  • 2 images apply_45

20:51 60
  • set flat
  • 175 modes
  • z5,6 0 4.2

  • flat_60.sav

21:06 75
  • Rest and set
  • apply_75.sav

  • 121 nm rms

21:28 90
  • two bumps, act 380, 376
  • 372 modes
  • Rest, Set 6234 modes, no bumps

21:34 75
  • from 90 flat to collect 4D set not collected above
  • 4d flat_75
  • flat_75_2.sav

Change elevation and take Flat.sav files to see which actuator jump

22:01 Move from 75 (no bumps) to 60
  • at 71 el start getting bumps at act 376 and 381
  • 60 El
    • jump_60.sav
  • act 556 380 jumps
  • 45 El
    • jump_45_force

    • jump_60_2.sav
  • 75 El
    • jump_75_2
    • jump_75_2.sav
  • 90 El
    • act 555 and 556 jump at 90
    • jump_90_2 image
    • jump_90_2.sav
    • 4D jump_90_556

Test M2/M3 positions from 20180620

23:15 Put old positions and see cat eye image. This must be a local minimum.
  • 3 images m2_m3_bad

23:41 Values for M2 and M3 are now in PSF and OSS configuration files

TN = ["flat_60","flat_45","flat_30","apply_45","apply_60","apply_75","flat_75","jump_90_556"]
