Agenda (tentative)

  • 0900 - 0910 CAD model update - Bob
  • 0910 - 0920 OIWFS performance model input parameter collection - Rich
  • 0920 - 0930 Science Team activities - Bahram


  • Rich discussed MOSFIRE cost accounting with Sean Adkins on Nov 4. They agreed a written request to Sean for his support in assembling costs would then lead to Sean's estimation of the effort (and potentially a request for project funding to support this effort).
  • Bob has made progress receiving updated thermal interface detailed CAD information from Vlad at HIA, though MOSFIRE demands continue in the near-term.
  • Rich has started from the ORD-CCR24 section (IRMS) to get a handle on the OIWFS performance requirements
    • The 80% EE limit is presumably an instrument requirement, not a NFIRAOS+IRMS requirement across the entire FoV, but this is to be determined.
    • A question regarding the necessary capture range for focus from the OIWFS arose - how out-of-focus might the delivered NFIRAOS beam be? Presumably NFIRAOS could use it's ACQ to do a coarse focus, but if the sodium layer is moving rapidly and theres lag between ACQ focus and getting light into the IRMS OIWFS, how far off might we be? - Rich to check on IRIS' assumption for this.
    • Rich will begin a document that will eventually capture the flow-down of requirements to OIWFS performance requirements.
  • Bahram is working on the science case, but without a postdoc is carrying this load single-handedly. Still, he has a goal of distributing this to the science team by Thanksgiving.

Meeting schedule

  • IRMS Team Meeting #8 will be Tues, Nov 29 at 9a
    • That agenda will include a review of the remainder of the project schedule, which is somewhat behind due to demands from MOSFIRE, SEDM, PALM-3000 and other projects.

Outstanding Actions

  • Rich to work with TMTO (Brent) to assess suitability of external OIWFS in terms of sky coverage and performance (by Dec 2)
  • Rich to make written request to WMKO (Sean) to support MOSFIRE cost detail in support of the IRMS estimate (by Dec 15)
  • Rich to contact UCLA (Ian) to request UCLA detail MOSFIRE cost breakdown (by Dec 10)
