Open Action Items

  1. Action on JH: Get from SciOpsIPT AI list


  • Attendees: JH, NM, HL, AW, TH, CB, CL, RI, EF (phone).
  • Apologies: Kartik (traveling to JAO)
  • Minutes from last meeting are posted at https://safe.nrao.edu/wiki/bin/view/ALMA/JAOsupportMinutes2011Aug25
  • Report from Chile
  • New Activities:
    • Revisions to Technical HB for Cycle 1. DSO has made chapter assignments (see also AssignmentsTechnicalHandbook.pdf). Need ARC contacts for review/input. Lets fill out list at end of agenda. JEH will try to get this filled out by going door-to-door
    • Documenting "common technical errors made in Cycle 0" for users to see for Cycle 1 (could be based on FlagsSheetforTA.draft1.pdf generated by Liz Humphreys after the August TA Workshop). Plan is to put this into a KB article to be deployed along with the Call for Proposals. Suggestion: break list into different parts and assign to different ARCs. In each ARC, assign each question to a TAWG member or participant from TA workshop. Carol will take lead in organizing our part.
    • Revised list of Cycle 1 Capabilities (DO NOT DISTRIBUTE). I'd like to collect any concerns about these to feed back to the project. The plan is to finalize these for an announcement to go out Dec 1.
    • We also have the configuration/simulation effort to discuss, but lets hold off on that until the ensuing Tiger Team meeting (ALMATigerTeamMtg2011Nov10). Items to flag: 2mo shutdown; too many spectral setups (CB to provide some words); much better definition of "Demonstration Science" call & process
  • On-going Activities:
    • Pencil schedule for CSV support: NAASC2Chile
    • P2G: we are in Batch3 prep period (Nov1-30).
      • JAO has not yet assigned projects to P2G members, even through Batch 3 prep nominally started 10 days ago!!! People and PI's were told to be available based on existing schedule, and have arranged travel accordingly. So JEH must remind ("insist" was used at meeting) JAO follow timelines (DONE). Harvey, for example, will be unavailable Dec 1-14.
      • Hoping to move to R8.1 before Batch 3 to fix infamous LO4 problem. However, SBs will be even LESS efficient in R8.1 b/c of innerscan overhead. Partially compensated by going to longer SB durations.
    • Calibrator Source Survey:
  • Next Meeting: Nov 18? (Nov 25 is Thanksgiving holiday)
