Mirror reflattening

mirror reflattened using: print, opt_int_mat_reduce(300,/mult,nmeas=5), flat data used: 2009_08_10

peak force=0.28N, surface error 37nmRMS, interf image saved:2009_08_28_reflattened300modes_37nmRMS.h5

shell ripped while closing the loop, new flattening command calibrated, same force and WFE as before

Noise, set "_a"

kl, set_b_noICC

as before

previous data to be replaced, start again with 'c' set

  • print, update_ovs(0.005)
  • print, set_icc(/reset)
  • make_modal_disturb(0,335,/KL,/SEND,EXT='c_noICC',/SAVE)
  • print, if_redux_pos('2009_08_28',0, 335,'_klfit_' ,'c_noICC')
  • .....iterating the sequence over modes 336 -->671 and over 'd' set

!! number of fringes on the interferogram increases during the measurements (since 10am to 12am)

kl, set_e_ICC

  • print, update_ovs(0.005) ---> when set again the ICC the shell came bach
  • make_modal_disturb(0,335,/KL,/SEND,EXT='e_ICC',/SAVE)
  • print, if_redux_pos('2009_08_28',0, 335,'_klfit_' ,'e_noICC')
  • .....iterating the sequence over modes 336 -->671 and over 'f' set

set '336_671_f_ICC' repeated twice as t the first attempt a wrong sampling frequency was detected. measurements set deleted and acquired again

noise measurements

2009_08_28_noise_f_ICC

safe_skip_counter =0

14:10 additional set of measurements wo ICC

this procedure was used:
  • print, set_icc(/reset)
  • print, opt_int_mat_reduce(300,/mult,nmeas=5), flat data used: 2009_08_10
  • print, set_diagnostic(over=0.005) that sets the OVS and does not set the icc
  • print, make_modal_disturb.....

14:50 additional set of measurements wo ICC

increasing the # of samples downloaded from sdram to 12000

series h, wo ICC

i,j, with ICC

k wo ICC (reset using print, set_icc(/reset)( NOTE: the subset 336-671_k is not present in the disk. Has been moved by somebody?)

15:30 strong convection structures visible on the interferograms
