Faults:

• Trouble deploying grism (K1-33244)

• LRIS red CCD not working (K1-33256 00:30)

  • Power cycle red ccd controller

• LRIS grating trouble (K1-33267 02:48)

  • Issues with turret encoder

• Multiple exposures on the red side failed (K1-33268 00:02)

  • Lrisplus not active

  • On this issue, mention observers of the limitations of running scripts (change of exp time does not affect all exposures)

• Some other faults not related to lris (magiq DSS and other issues)

WORK DONE:

• Examine grating encoder. Put the encoder on a PDU (slot 25)

• Checking CMDLRIS

• Open

  

  Improving polarimeter operations

TO BE DONE:

• GUIs

• Recreate the focus table (ongoing)

• Monthly Checkouts (new run starts on June 11with Chien-Hsiu)

• Power cycle blue side

  Open

  

Other Items:

• Refurbishing plans. This has been delayed due to shortage of staff.

• Prepare CI for:

  • Polarimeter controllers (API to Galil)

  • Autofill system

  • Maskcutter spare

• UNO checks.

  • New checkall -> feed keyword

  • New checkall includes mask verification

• XLRIS version. Final review of cmdlris

• Autoslit

• Power control:

  • Needs to include the grating turret encoder

  • Blue crate needs to be added to keyword system

• New lredccd
