2019022 Day DX 4D alignment and Flat Measurement.

4D Alignment

17:00 UT Alessandro align the 4D expanding beam to the center of the tertiary
  • Looking at 4D image, illumination is offset from the center. Alessandro sees the same thing looking at the outgoing beam of the 4D
  • Alessandro checked and fixed the laser fiber plug. All is good

19:00 Collimating the M2 Hexapod with the old values from September does not get the return beam.
  • Use M2 numbers from August. See part of the pupil
  • Move the hexapod in DX and DY to get mostly filled pupil on 4D
  • Set the Shell. Full pupil seen

20:00 on DX AdSec machine
  • sudo mount -a
  • now /local/aomeas_DX/adsec_calib/4d directory is mounted from the 4D machine

20:4Sight server start
  • Run default script (D button)
  • Tools->debug->Open 4Sight Scripting Consol
  • >>> from I4D import comm4d
  • >>> from I4D import Constant4d

20:18 Start client on DX AdSec machine

20:28 Move M3
  • M3 Tip +20
  • M2 0.033598931 0.037878274 0.0022596926 -9.0364240 6.7074807
  • correct direction. Maybe 2 pixel down with pupil. Need 25-30

20:44 Move M3 and M3 DX,DY manually

22:04 Flatten with old Recon
  • print, opt_int_mat_reduce2(20, track='20180828_123635') - 0.002 N OK
  • print, opt_int_mat_reduce2(100, track='20180828_123635')
