Instrument Released for Partner Science

• MODS
  • Caveats
    • Some refinement of focus may be needed
    • IT 6386 - sequecner issue of MODS2-Blue - intermittment - not clear if frequency is increasing, although it happens at the start of every night
    • SYNCOFFSET for image dithering needs work - if one MODS or MODS channel is slow, the SYNC offset will hang, removing SYNCOFFSET may result in telescope moving before an exposure finishes if one channel is too slow, as well as violating co-pointing limits (known issue)
    • MODS1B as of 08/27/20 is offline - repair of microlynx controller needed for grating turret - IT 8171
• LUCIs
  • Caveats
    • New Flexure and Wavelength tables not updated (flexure should not have changed with LUCI-2)
    • Co-pointing limits have to be diasbled for big dithers (PCS issue)
• LBTI
