Night Info:

• Split night between LBTI AO-onsky checkout, D/E tasks.
• Night Center: 00:04
• Handover from LBTI to LUCI-2 checkout: 23:59
• Moon rise: 21:48
• Sunset: 17:39
• Twilight ends: 18:58
• Twilight starts: 05:10
• Sunrise 06:29

Night Plan:

• LBTI on-sky checks until 23:59
  • thin clouds
  • seeing < 1.2"
• LUCI-2 checkout starts 00:09
  • Rotator ZP - via astrometric masks - 0.5hr
    • thin clouds, seeing < 1.2"
    • Stone O (from UT 2021-10-07) - theta = -0.01 star#36 rejected)
    • Stone P sets 00:15 (30 deg)
    • Stone A sets 02:20 (30 deg) - worked best without any stars rejected for LUCI-1
    • Could test other LUCI MOS masks for extra datapoints or LS test
    • Files needed: ssh -X into obs1 as telescope; then ssh - X as tcs@tcs1
      • /home/telescope/TCS/Configuration/PCS/PCSInstrument.conf
      • Bounce GCS and PCS
  • AGW Transform - 1-1.5hrs
    • thin or variable clouds, seeing < 1.2"
    • Transform Collect
    • Potential lists:
      • Stone_A3_LUCI.list - sets 02:20
      • Stone_C1.list - RA ~04hr Dec -01 - sets twilight
      • Stone_D_new_Oct27.list - RA ~04:30hr Dec -00 - thru twilight
      • Stone E (-90,-135,90, 0 PAs) - RA 07hr Dec +00 - 01:30hr-twilight
  • Photometric standards bino-LUCI if poor seeing but clear
• MODS
  • IT 8472 - GS at left edge of patrol field - 0.25hr
    • any conditions, but see below if photometric
    • Run sdss04+51_phot.txt in /home/lbto/Service_Observing/2021B_D_E/MODS
    • Takes 30-sec exposures at g+u(2x) and riz.(need star bright enough to WFS/guide on). We could make use of photometry since the field is in SDSS DR12.
• LBCs
  • Active TMS - 3hr
    • Instructions
    • any conditions
    • start the night with a previous reference (the reference from 20211014), note the corrections indicated by dohybrid.
      • reference is tms?x_ref.dat_ and is in telescope@robs.mountain.lbto.org:~/TMS_logs/20211014/
      • on robs as user telescope, cp ~/TMS_logs/20211014/tms_?x_ref.dat /tmp
    • track a field through a large elevation change for ~2 hrs
      • Choose GD_279 or J031900+43. The scripts will dither 6x and change filters. You would need to repeat the OB about 4-5 times to make up 2 hours on the field.
      • visibility plot: 2021_oct26_2stds_vis.png
      • Scripts in: /home/lbto/Service_Observing/2021B_D_E/LBC/New_PhotFields/Scripts
      • Dual purpose: Please note whether it is photometric or not since these fields are from the set of new phot stds.
    • slew to a few fields at different elevations with TMS in active mode. Run FPIA and note the corrections indicated.
      • Use copointing fields for new phot standards.
      • Want to change elevation (see vis plot png or OT New_Phot_Fields_Master_OT_V1.1.xml).

LUCI Checkout

UT 05:58 - reconfiguring for LUCIs

-start with Stone P - putting MOS mask in FPU to save time while we reconfigure

LUCI-2 MOS Error

Error moving Mask 18 to FPU El 90 Rotator = 210

Post Condition Violation Exception MHU absolute angle

NOT True that motor is at required position

picker arms open - everything is locked - this was going to grab the mask.

Position 18 -12888 current position -12887

Translator angle should be 24.3, current position is 24.67

Initializing the MOS since nothing is open nothing unlocked --> move the robot to a knonwn position

Cleared it - moving to grab mask again

UT 06:12 - config to LUCIs done

LUCI-2 Rot ZP

UT 06:14 - pointing check

StoneP

-seeing on guider is borderline, but its also low - will give it a try and move to next MOS

#36 looks like worst fit in RA - removing it

#33 next worst, removing it (also faint), removing #35

0.76", -2.28" theta = -0.028 err 0.055, 0.047 Seeing on Guider is 1.2"-1.5" during acquisition

Looks Good

StoneA

UT 06:33 - moving to StoneA

Guider is 1.38", WFS 1.16" - borderline again

seeing down to 1.09" on guider, 1" on WFS

Good fit with all points

0.399", -2.904" theta = -0.050 err = 0.055, 0.055 guider ~1"

Looks Good

NO UPDATE TO ROTZP Needed

AGW Transform

Resuming Observing

UT 10:35 - winds below llimits - will go to a new field

• starting the loop again tms_loop.pl
• heading to field to run dofpia
• running dofpia
• do copointing

- don't seem to be sure if TMS should be stopped before doing DOFPIA - discussion going on whether DOFPIA and TMS might have fought each other - we ran DOFPIA while TMS active was going on

-the copoint images have coma and look bad, particularly blue

• CTRL-C 2x TMS
• Running DOFPIA again
• PRO TIP: DO NOT KEEP TMS RUNNING WHILE DOFPIA IS RUNNING - PAUSE TMS FIRST
• Running OB for field
• Upon arrivel - run setpoint
• Now run TMS active loop

LBC-B 1.33" FWHM, LBC-R 1.52" FWHML

UT 11:22 - taking set #2

• setting TMS active
• sending preset and letting it go

UT 11:43 - starting set #3

-skirting the wind limits again

UT 12:03 - starting set #4

UT 12:07 - out of focus

• stopping script and TMS
• hit CTRL C in the wrong window - OT
• re-running DOFPIA
• sending preset and stop
• set point
• starting TMS
• sending preset again - UT 12:21

UT 12:25 - Blue showing a lot of coma, Red looks good

UT 12:26 - stopping and running DOFPIA again

• settingp point
• starting TMS active
• sending preset again UT 12:34

UT 12:37 - blue still has coma, red looks OK

UT 123607 - LBC-Blue scrambled

Hardpoint error message on SX Primary - could this be affecting and/or causing the blue coma

LBC-B 124438 - double image - jump? trail?

UT 12:53 - images are saturated in red- script finishing now

UT 12:54 - closing dome
