DX Reconstructor Measurements

  • Getting Started
  • Source found nearly the same spot as yesterday.
  • New Flat, so that I can start on Bin4: 20190105_400_mode
  • idl_65383 |INF| 730|2019-01-05 17:32:42.766637| MAIN > Maximum mode index used to apply flat -> # 0
  • When it did apply properly, It didn't look very good. Trying again.
  • Flat: 20190105_400_mode_2
  • idl_65383 |INF| 895|2019-01-05 17:36:35.209387| MAIN > Maximum mode index used to apply flat -> # 324

  • yesterday's flat looks best: 20190104_400_mode
  • idl_65383 |INF| 1004|2019-01-05 17:40:08.821944| MAIN > Maximum mode index used to apply flat -> # 634

  • Now to bin 4
  • 10 Mode, open loop: using Amplitude file: 672_03
  • Disturb:20190105_174546
  • Intmat:20190105_174616
  • Recon:20190105_174745
  • Forgot to change Pupils
  • 10 mode open loop.
  • Intmat:20190105_175220
  • Recon:20190105_175351
  • 10 Mode Closed Loop
  • Intmat:20190105_175650
  • Recon:20190105_175817
  • Looks good
  • 36 Mode: Closed loop with 10 mode recon:
  • Disturb:20190105_180138
  • Intmat:20190105_180310
  • Recon:20190105_180455
  • Looks Very Good
  • 36 mode with 36 mode closed loop
  • Intmat:20190105_180825
  • Recon:20190105_181009
  • Looks fine
  • Now with 48 iterations
  • Intmat:20190105_181334
  • Recon:20190105_182632
  • I'm not satisfied with how the modal plots look, I'm going to up the amplitude and try again
  • Disturb: 20190105_182929
  • Intmat:20190105_183014
  • REcon:20190105_184309

  • I want to look at bin1 again.
  • I'm going to use a higher amplitude file to make the disturbance, 4 iterations first: 672_0.7
  • Disturb:20190105_185038
  • Intmat:20190105_185210
  • Recon:20190105_185437
  • That looks improved around the edges, trying 48 iter
  • Intmat:20190105_185654
  • Recon:20190105_191131
  • There is an odd effect with the higher order gains, they are set to the minimum possible amplitude, but the correction looks good.
  • I think that having the amplitude that high is causing that effect.
  • Trying with 672_0.35
  • 48 iter
  • Disturb:20190105_192114
  • Intmat:20190105_192252
  • REcon:20190105_193618
  • Trying a big Modulation, to see if I can fill the persistent hole on the left side.
  • Rotator 201.743
  • Nope, back to 22.223
  • Flat: 20190105_400_mode_3
  • That may have it.
  • 48 iterations using Rec_20190103_214048.fits
  • It makes the smallest hole on the left.
  • I'm going to try the doug_400_2l_0.6 again, it had good results.
  • Disturb: 20190105_201113
  • Intmat:20190105_201242
  • Recon:20190105_202601
  • Not quite stable.
  • One last try. optimized_amano_6l_per1.5
  • Disturb: 20190105_204358
  • Intmat: 20190105_204514
  • Recon:20190105_204646
  • 48 iterations, after much testing.
  • Intmat:20190105_210926
  • REcon:20190105_212247
  • Forgot to switch the stinking actuator map!
  • Disturb:20190105_213340
  • Intmat:20190105_213445
  • Recon:20190105_214824
I could not get a satisfactory Bin 1 reconstructor. There are still big bites all around the secondary that I couldn't get out with any number of flats. Also We need to re-do Bin4 as I had the wrong actuator map in. (Doh!) Anyway, I want to talk to Doug and Guido before we decide how to proceed.

Note the image of the modes and the pupils. You can clearly see where the bites are.
