Old Business

The enhanced Agenda from last month's meeting is available. Science IPT notes from last month's telecon. Last Meeting Action items
- Action items from various sources:
Last month's Science telecon:

ACTION: Wootten get with DTE on satellite. Wilson wrote an email introducing the topic to him. Done
ACTION: CSV plan and canvass. Laing provided the plan to Japanese colleagues. Done
ACTION: John will work on the antenna location plan In process
ACTION: Science IPT telecon date change to third Tuesday. 20 Apr Stay constant in local time, change in UT. Done

SE telecon. ACTION: [Wootten]- what is the required IDR for a single image. Bring this up in the science telecon.
ACTION: Science IPT, [Laing]- produce short memo on origin of spec on differential gain stability. [N.B. ALMA Tech Requirement No. 264 Differential gain stability between channels of a polarization pair 5e-4 at 300 sec TBC allocation to FE and BE are each 0.707 of this value 320 23]

ALMA Week: [Wootten]Provide detailed values on solar filter to FEND by 30 April
[Laing] Develop a requirement for stitching together the BEND 2 GHz sections for overlap.
[Conway, Laing] Choose antenna stations where first antennas will be located for first fringes. 4-30-04 [See CSV document]
[with SE] Decide when antennas are handed over to Commissioning (after 1st light or 1st fringes?) 6-01-04
[Wootten & Co] Write System Review Report In process

MILESTONES: all leaders of level 3 milestones with upcoming deadlines to report on status. The Milestones, with project number, are available updated for March.

    -2 Calibration (Mangum)
      - The Requirements and Specifications August 03 Version (Wootten)
      - Draft Bandpass Calibration Memo. from Bacmann and Guilloteau (2 of 3 reviews, both favorable, received)
                  - Very drafty Calibration plan.
      - Plan for further tests of amplitude calibration devices:   Progress? (Martin-Pintado)
      - Discussion of Mark's (Holdaway) which argues:
   ACA baselines are so short that you don't need phase calibration.
       The Weather is so unpredictable that the ACA needs dynamic scheduling.
       Fast switching won't help the ACA.
       WVR could help increase the efficiency of the ACA.
BUT:
        If the ACA is going to get correlated with ALMA,
          the ACA antennas absolutely need fast switching and WVR.

-3.Design Reference Science Plan (Hogerheijde )
Review of calibration questionnaire responses--50% have had replies. See link.

-4 Imaging (Gueth, Holdaway)
- IDR What Image Dynamic Range should we place a requirement on for a single ALMA field? Or should we? Request from SE.

   -5. SSR (Wootten, in lieu of)
       - Minutes of last week's meeting.

   -6. Configurations (Conway)

A draft version of the Spec document of ALMA first science configuration

-7 Site (Radford, Nyman)
- Summary of min, max temperature and barometric pressure range
- ICDs

-8 Operations, Science Commissioning and Verification (Laing)

- Draft ALMA Commissioning and Science Verification
