We did some closed-dome tests of binocular collimation in mixed instrument modes.

Details

Binocular Collimation Tests

Mirror positions are recorded in telemetry.

LBC-Blue and LBC-Red

Already authorized LBC and LBC

03:02 Preset both

LUCI1 and LUCI2

03:06 Authorize LUCI and LUCI

03:08 Preset fails because DX M3 didn't move?

03:10 Preset both succeeds.

LUCI1@LFBG and LBC-Red

03:13 Authorize LUCI1@LFBG and LBC-Red

See Issue 4795 for checkboxes not propagating.

03:26 Syncronized presets -- as expected, we hit -X limits on DX M1

03:28 Send Coma-free pointing correction to DX M1 only. Tilt=+10; Tilt=+20; Tilt=-20; Tilt=+30 arcsec

03:32 collimation good on both sides

LBC-Blue and LUCI2@RFBG

03:35 Authorize LBC-Blue and LUCI@RFBG

03:38 Syncronized presets - Note that this does NOT drive SX M1 into limits as you might expect from symmetry.

LBTI and LBC-Red

03:43 Authorize LBTI and LUCI@RFBG

03:44 Syncronized presets

LBTI and LBTI

03:49 Authorize LBTI on both sides

03:51 Syncronized presets

03:55 end of this data - park telescope
