NCPA measurements with LUCI2

12:40 Started setting up system

01:20 All systems on, AO and LUCI, however, cannot turn on ARGOS SX light source. Call Gustavo and Alfio email Jose, Martin, Wolfgang.

01:40 Lorenzo start needed processes

01:50 We have light on LUCI2 N3.75.

02:00 All parameters are the same as yesterday, but the spot on LUCI2 is up about 1". No light on acquisition camera

02:15 In order the move the spot on LUCI2 N3.75 camera to the center we can move the hexapod, but would have to move the WUnit stages to even further from its center position.
  • It appears that from March to Monday/Tuesday the spot shifted about 45" up and little to the right
  • This morning it moved another 30" up.

02:30 Things we checked:
  • Init and home M2 hexapod (no change in position)
  • Init and home M3 (no change in position)
  • Retracted and deployed ARGOS swing arm (no change in position)
  • Changed from N3.75 to N30 and back to N3.75. (no change in position)

04:33 Alexander online and adjusted the flexure compensation mirrors to see if this is the problem
  • Yes, could move image around
  • Set it so it was close. Now the star on the N30 camera is down and to the left of the center of the chip. This will move WUnit stages toward the center position.

04:50

Angle X Stage Y Stage Preset X Preset Y
30 -71.5 -54.5 -4 -4
90 -72 -55 -4 -4
150 -71.5 -56 -4 -6
210 -70 -55 -10 -30
270 -47 -57 -30 -6
330 -75 -56 -1 -5

05:00 motion on LUCI2 and Stages
  • LUCI2 N357 1 pixel = 0.125"
  • LUCI2 N30 1 pixel = 0.15"
  • Stage 1" = 0.6 mm

05:05 move start @ 270 degreed to the center to the chip (move star right)
  • Moved Hexapod -120 to -300 to move LUCI star from straight left of center to center
  • 300 pixels on LUCI2 (~30")
  • moved stage from -47 to -68 mm in Y (~20 mm)
  • near center on N375
  • Tom put in N30
  • Move star to the right with hexapod (Rx -300 to -330)
  • move stage Y to -72
  • Final XY -72, -56
  • preset values -3, -5

05:15 Preset, AcquireRef, StartAO OK
  • apply Z5=38, Z6=75
  • Tom set subwindow
  • Star nearly in center of subframe

05:30 Turn over telescope to mountain crew for shutter door inspection
  • Tom put Blind/Blind filters in
  • I turned off CCD 39 & 47 little joes. Will power on when start again and PresetAO should re-initialize.

07:32 Collect data at 270
  • Z4 = 0
  • Z5 = 50
  • Z6 = 63
  • Z7 = -16
  • Z8 = 0
  • Z9 = 0
  • Z10 = 0
  • Z11 = -9
  • Done at 09:09
  • Saved as 20150422_270.fits
  • SR max = 0.69

09:09 Move rotator to 330

09:35 Collect data at 330
  • Z4 =
  • z5 = 26
  • Z6 = -116
  • Z7 = -9
  • Z8 = 24
  • Z9 = -7
  • Z10 = 10
  • Z11 = -9
  • Done at 10:43
  • Saved at 20150422_330.fits
  • SR max = 0.95

10:50 ARGOS swing arm retracted, handover
