LUCI-Bino

  • UT 07:36 - OCAM cooled down
  • D.G.Huerta will run the OSCO
  • UT 08:01 - pointing star
  • UT 08:06 - some issue with re-authorization not working right
  • UT 08:07 - now presetting to pointing star
  • UT 08:13 - collimation preset....let's see what's behind Door #1!
    • star too bright - SH spots are blased - picking fainter star
  • UT 08:18 - Guider shows 1.4" WFS shows 1.2"
OSCO
  • Sending preset to BD +70 622
  • UT 08:29 - Rmag 7.48 WFSmag 8.9
    • some safeskips
    • one dark spot on mirror gui momentarily - so far no rolled edges
  • UT 08:34 - trying NCPA - sending absolute offset to return back to initial position
  • UT 08:38 - continuing ... 2nd dither w/NCPA
  • L1 0037 - loops were paused
  • L1 0038- reclosed the loop
  • L1 0042-0043 - loops opened
  • UT 08:44 - some rolled edges on optimize gain - G.Taylor still trying to re-close the loop
  • UT 08:47 - continuing for three more frames

Bin 1 on-axis star BD+33 2137
  • R=10.3
  • PA=0
  • White Dwarf
  • UT 08:52 - sending preset
  • UT 08:56 - missed the guidestar, checking pointing
  • Generated a new script - PA=60 to avoid GS guiding in offs
  • UT 09:00 - sending preset
  • preset failed - AGW probe warning - but GS is well within the FOV
  • UT 09:05 - choosing another PA=240 for a brighter R=13.9 guidestar
  • Either we lost collimation or the seeing exploded from 1.3" to 4"
    • guider is down to 1.7", still collimating - settled at around 1.8"-1.9" - guess the seeing did explode
    • Now 1.16", 1.4" - just unstable
  • WFMag = 13.1, closing with Bin2 as its more stable
  • getting safeskips, but routine is forcing a higher gain
  • UT 09:20 - still struggling to close the loop - highly variable conditions
    • G.Taylor setting gains manually
    • seems like the auto-gain routines are just making things worse
  • UT 09:25 - closed the loop
    • hit done but didn't return to LUCI
    • LUCI timed out, skipped to next line and hit GO
    • looks terrible - too few counts - changing to H-band filter and continuing
    • some frames look good, some look terrible
    • do 1 more exposure then find another Bin 1
BIn 1 ON-Axis HD 90360
  • R=8.9, will need subframe 256x2048, WFSmag = 10.8
  • PA=0
  • UT 09:37 - preset
  • getting rolled edges and loop opened
  • UT 09:46 - G.Taylor reclosing loop - testing subframe
    • Suggestions for RTD Panel:
      • Change "GET" button to "Select Position" or "GET COORDS"
      • Swap positions of the "Draw" and "Reset" Buttons - more intuitive this way
      • Get rid of the Send to Geirs rectangle
        • change the NEW SUBWIN button to "SEND TO GEIRS"
        • change "Full Frame" button - to "Reset to Full Frame"
      • Remove scroll bar for Overview info - use the empty real estate to just state the current config (e.g. 256x2048)
      • Not sure what "Type" refers to? it says "AFC Pinhole"
      • Don't need X/Y PIX
      • What does "Group" and a "-1" refer to?
      • After clicking the NEW SUBWIN - the drawing overlay vanished - bug? feature?
  • Was to keep with FeII, but max count is 42k with FeII - so will manually change to H-band for 256x2048
  • UT 09:48 - loop closed
  • UT 09:49 - Shell RIP'd - seeing must have improved - peak count with H-band now 54k will put FeII back in
    • G.Taylor recovering RIP
  • UT 09:57 - resending preset
  • UT 09:59 - DIMM reports 4", guider reports 1.83"
  • UT 10:01 - DIMM back down to 1.4"
  • UT 10:05 - closed as BIN 1
  • UT 10:09 - taking data!
  • UT 10:10 - loops opened - gains were too high (thank you auto gain)
  • UT 10:13 - brief rolled edges
  • UT 10:13 - continuing script
  • UT 10:17 - turning on NCPA now (L1 0058)
  • PSF looks really good
  • UT 10:19:30 - preset failed on 100",100" offset - guiding did NOT pause - it tried to find the guidestar - offset faled alert and preset fell back to ACTIVE
    • we didn't move - so why did guidestar vanish?
    • Seeing did not blow up
    • the first offset to "sky" the GS is at the edge of the patrol field
    • sending offset 0,0 Absolute
    • this fixed it - skip, the 100,100
  • UT 10:27 - skipping to a "good" offset where we are not in danger of accidentally keeping the GS - got the good "bonk"
Bin 1 On-AXIS BD+00 2888
  • R-10.74, PA=0, subframe=256x2048, WFSMag = 11.5
  • UT 10:34 - sending preset
  • Guider before closing loop = 0.89"
  • UT 10:43- doublr or jumed image?
    • 0.225" separation diagonally - G.Taylor does not see this on CCD47 - tried rebinning it and everything conked out - think this is real
  • UT 10:48 - continuing after loops opened - will find another star
  • decied to just move to the next star
Bin 1 On-Axis PG1530+212
  • UT 10:56 - preset went after I clicked abort - odd
  • Taking a while to abort this through TCS
  • UT 11:01 - sending preset
  • Rmag=11.2, WFSMag=12.9 , PA=120
  • SX Guider shows 1" before closing the loop
  • Ended up as Bin 2 - G.Taylor forcing to BIn 1 lets see what happens
  • few percent safeskipping
IC 3583 - Bin 1 off-axis (17") - Pretty Pic Candidate
  • UT 11:20 - sending preset
  • Rmag=10.55, WFSMag = 14.0
  • Guider 0.96"
  • WFS is paused - locking out AO - aborted wait for collimation on Telsvc and OSA canelled script
  • UT 11:28 - resending script
  • There is another star 55" away that is R=11.14 (in UCAC5), other AO Ref star only in NOMAD - will generate new script with this
  • UT 11:34 - cancelling this AO preset for revised script
  • UT 11:36 - sending V3 preset
  • looks like its going to BIn 2
  • Rmag=11.14, WFSmag=13.1
  • Punting this - would need longer exposures to see anything - (despite the fuzz one can see in 2MASS) - the star that came up as R=10.55 and K=11.8 doesn't seem to have been as bright
Bin 3 On-Axis - GD 187
  • WD, Rmag=15.0, WFSMag=16.4 , PA=60
  • UT 12:02 - letting script run through
  • L1 0079 - PSF looks very trefoily...
  • GOpt seems to be addng astigmatism, Rotator=151
  • Lots of astigmatism at this rotator angle
Bin 3 On-Axis PG 1325+102
  • Rmag=14.29, WFSmag=15.8 , PA=0
  • sdB dwarf
  • UT 12:25 - sending preset
  • Re-rotator out of range - rotator = -18.7
  • moving rotator +200 degree and will resend the preset
  • UT 12:29 - sending preset again
  • Rotator angle =338
  • FWHM from RTD ~0.07"
  • seems a consistent FWHM~0.07" in frames
  • FWHM has degraded a little to FWHM~0.09" L1 #104 looks a liitle stretched and elongated
Bin 1 On-Axis BD +00 3109
  • Rmag=10.23, WFSMag = 11.7, PA=240
  • G-type star
  • UT 13:01 - sending preset
  • No guidestar found - checking pointing
  • UT 13:05 - re-sending preset
  • guider shows 0.57" before closing the loop
  • Looks like it jumped - i don't think this is a double star L1#107 - between NDIT 6 and 7 it jumps in an orderly way - very orderly it moved right and then down
  • Bin1_Jump.png
  • PSF looks wonky -L1 #109 - lots and lots of trefoil - is it just NCPA needed? Rotator = 219
  • Bin1_wonky_PSF.png
  • UT 13:20 - got a safeskip - L1 #0111 - loop opened
  • L1 #112 - may not be good
  • WFSMag = 11.7 still, so twilight light isn't significantly impacting
  • UT 13:28 - stopping now since well into nautical twilight
  • UT 13:38 - dome closed and done for the night - putting LUCI-1 into safe config for CABEX
