Night Plan

  • Handover from PEPSI/PETS - 00:53
  • Reconfigure for LBCs - 00:53-01:13
  • D-time Science
    • Death from Above! (Potentially Hazardous Asteroids) LBCs w/TMS
    • no guiding to be used
    • non-sidereal mode
    • OT file location:
    • Four targets (one script per target - the object name is in the name of the script)
      • (3 exposures of 180s each for each target)
    • NSIGUI names to use:
      • 2013 LM31
      • 2017 VW13
      • 2018 LB1
      • 2019 XO2
    • Cycle through the four scripts, hopefully twice (there should be enough time)
  • Reconfigure for MODS-Bino - 02:45-03:15
  • D-time science MODS-Bino - Dual BLR 03:15-twilight
    • Requires seeing < 1.2", up to thin clouds
    • /home/lbto/Service_Observing/2022A_D_E/LUCI/DualBLR/Dual_BLR_ESM_MODS_V3.xml
      • LUCI and MODS scripts are all in same LUCI directory
    • DualBLR SDSSJ1713+3256 MODS Dual Grating 1" slit
    • Finder Chart: SDSSJ1713+3256_MODS_Finder.png
    • PA=264.4 so that both small and bright nuclei are in the slit.
    • Use the FAINTER/Smaller nuclei for modsAlign, this avoids placing it on the CCD quadrant boundaries - the brighter nucleus will be above it.
  • Spectrophotometric Standard - Astro Twilight
    • BD+33 2642 - Dual Grating
  • Other D-time science (rolled over from earlier)
    • MODS-Bino mid-z ULIRGs (two objects visible from handover until 03hr - 1.25hr each

Backup Poor Weather

  • End of night - (last hour before twlight) - V1674 Her Followup - MODS Bino - M.Wagner
    • if 1.2" < seeing < 1.8" and clouds 1-2mag
    • OT Files and finder chart: /home/lbto/Service_Observing/2022A_D_E/MODS
  • Rothberg Local Mergers - LUCI-2 (bino LUCI if available)
    • OT: /home/lbto/Service_Observing/2022A_D_E/PoorWeather/Rothberg/LocalMergers/COBandhead_Mergers_V42.xml
    • Finder charts in directory
    • Not in order of priority - choose based on visibility
      • NGC 4004 - twlight-04hr Dec +27
      • NGC 6598 - 23:30-twilight Dec +69
      • UGC 9829 - 01:30hr-twilight Dec -01
      • UGC 10607 - 01hr -twilight Dec +26 (use "earlier" telluric)
      • UGC 10675 - midnight-twilight Dec +31 (use "earlier" telluric)
    • Run about 1hr in monocular mode -longer if thicker clouds and/or poorer seeing
  • LUCI Photometric Standards (any seeing, if so bad can't guide, use track mode) - requires clear skies
    • mono or bino LUCI
    • pick based on visibility and getting two airmasses (widely separated) minimum
    • /home/lbto/Service_Observing/2022A_D_E/PoorWeather/LUCI_Phot_Standards
  • MODS Spectrophotometric Stds and Photometric Standards
    • only if clear
  • LBC Photometric Standards
    • only if clear
