Measure SX FF Matrix and Flatten with 4d

21:07 Tested new 5 iteration FF matrix
  • Looks good at least in terms of flatness (no bumps around outside edge)
  • Only 202 modes with new FF were had 572 with old FF
  • new flat with 4D should give and improve flat (shapes, bumps) and lower forces.
  • Sent email to AO group on Sunday, Aug. 27 at 1:58 pm "New FF Matrix on SX looks good"

21:11 Checked configuration file $ADOPT_ROOT/calib/adsec/current/scripts/ff_acquire_default.tst
  • n_cycles = 20
  • file names are given (no "")
  • modal with FF

21:30 Elevation drives are locked out
  • kill adsecarb process
  • enable_lab_mode.sh

21:30
  • AdOpt> print, fsm_rip()
  • AdOpt> print, fsm_set_flat(/ff, /no_flat)
  • AdOpt> print, collect_noise_data()
  • Data saved in: /local/aomeas/adsec_calib/noise/20170827_213323/noise_lin.sav

21:34
  • $ aoidl
  • IDL> @startup
  • IDL> restore, /VERB, "/local/aomeas/adsec_calib/noise/20170827_213323/noise_lin.sav"
  • IDL> sigma_pos_reb = sqrt(rebin(sigma_pos^2, 672, 1))
  • IDL> display, sigma_pos_reb, /SH, /NO_NUM
  • image
  • IDL> display, sigma_pos_reb[adsec.act_w_pos], adsec.act_w_pos, /SH, /NO_NUM, MIN_V=4e-9
  • IDL> print, where(sigma_pos_reb[adsec.act_w_pos] GT 5.e-9)
  • 540
  • IDL> print, adsec.act_w_pos[540]
  • 550
  • IDL> print, sigma_pos_reb[550]
  • 5.0834261e-09
  • Actuator 550 is near the limit to leave in pos use. Will measure 20 iteration FF and see what its noise looks like.
  • Need to correct FF document to use adsec.act_w_pos variable

22:12 Measure 20 iteration FF Matrix
  • AdOpt> tn=tracknum()
  • AdOpt> print, tn
  • 20170827_221420
  • AdOpt> print, ff_acquire_v2(tn)
    • => should have taking an offset before starting
    • => will try to take offset when first iteration is done
  • Took offset and now pos display looks better

00:30
  • AdOpt> print, reduce_ff_data('20170827_221420', /DO_PLOT)
  • normalized chi^2 ff_matrix: 136
  • images

01:31 copy new ff .fits files to data directory used
  • cp /local/aomeas/adsec_calib/ff_matrix/20170827_221420/*.fits /home/aoeng/act_add/calib/adsec/current/data/.

01:36 Stop and start adsec processes
  • Set Shell
  • flat 20170710_400_1.sav
  • 230 modes
  • Highest current of -0.29 at act 6. This was added back in use of the FF matrix. Then next highest force actuator was at -0.15. Hopefully new flat will improve this

01:58 FF matrix measurement complete for SX
  • Must copy the new ff .fits files to svn
