SX Testing of new BCU firmware in closed loop

14:58
  • Getting started
  • Rotator Angle: 341
15:25
  • Found Spot and closed loop with 20160229_184300 reconstructor
  • Baysidex: -70.025, Baysidey = -50.016, Baysidez = 54.600
  • Hexapod: 4.500 3.100 -0.0627 -67.26 12.12 0.000
  • Estimated Magnitude: 9.4
  • 1st test passed, loop closed successfully.
05:32
  • Setting up for LUCI image.
  • N30 camera, no fieldstop, FeII and clear filters, 2.5s exposure time.
  • Dark taken with blind/blind. 1Ndit, 1exp
  • Dark frame: luci1.20170323.0154.fits
15:34
  • Image off of N30 frame, going back to N3.75 to center.
  • Using crossed filters, Z and OH1060, to avoid persistence.
15:48
  • Loop opened for unknown reason.
  • Re-optimized gain 0.94 0.55 0.30
15:53
  • Actuator 150 has high current, 0.37.
  • Strange feature in commands at 11:30 position

16.14
  • Found suitable spot in N30 frame
  • BaysideX: -78.5, BaysideY: -44.5
  • Hexapod: 4.500 3.100 -0.0565 -58.1500 86.500 0.000
  • Gain: 1.09 0.50 0.30
  • Using Filters HeI and Z
  • Need Longer exposure with these filters
  • 20 Second Exposures gives peak value of 3000.
  • Baseline Optical Loop Data: 20170323_162146
  • Luci Frame: 158
16:25
  • Testing now with NCPA
  • Disturb: CmdDisturb _20160314_190412.fits
  • Dataset with GOPT off: 163701
  • LUCI Frame, GOPT off: 159
  • Changed to 30 sec exposure
  • LUCI Frame 161
  • GOPT on
  • GOPT gain 0.47
  • Loop gain 0.56 0.24 0.15
  • Dataset: 163853
  • Luci Frame 162
  • NCPA ON
  • Dataset: 164022
  • LUCI Frame: 163 BAD, Tip tilt overdriven
  • Lowered TT gain to 0.51
  • LUCI Frame: 164
  • New Dataset: 164228
16:43
  • Disturb: dist_flao2_KL_v18_atm_s0.8_L040.0_v15.0_ovfreq1000.00_sd1983.fits
  • Optimized Gain: 1.13 0.50 0.50
  • No GOPT
  • Dataset: 165555, 165857, 165952
  • Luci Frame: 167
  • There is no GOPT with this disturbance, so we are done. (LN was chomping at the bit to lockout the telescope.)
  • 30s Dark: 169 (skipped one to clear out any persistence)
  • 20s Dark: 170
