Project Scientists

  1. Science IPT -
    • Nutator SRR in Charlottesville 22-23 Jan 2007
    • "PSI/ATF Workshop" The dates are 24 and 25 of January 2007. Agenda
    • Face-to-face meeting in 2007 Q1? At AOC?
    • Antenna Spec Changes: ACA 7m Discussion
    • Schedule, etc. Current Science IPT Schedule
  2. Operations Working Group documents are available. Status Report. Development Wish List section for written expansion or comment. These are items whose development was postponed for lack of funding, mostly. Within the next year or so, a document will be written to develop these ideas and others. At the meeting, other items were discussed, including
    • Advanced WVRs with pointing correction capability
    • Increased data rates (especially desirable for use with new correlators)
    • Multibeam receivers.
  3. Astronomer Outreach: NRAO Newsletter ESO Newsletter NAOJNews. NRAO ALMA Calendar
  4. ARCs.
  5. Group Activities (all)
  6. Next meeting is on Feb 21st (14:30 UT). 21 March for the following month.

Emerson/Laing/Vila-Vilaro -- Instrument Scientists

  • PSI at the ATF: Schedule, progress wiki. Daily Logs Kudos to Darrel and his merry men for the outstanding job they have done with holography and the preparation for using it on the production antennas.
  • During the ACA Correlator CDR the possibility of SIMULTANEOUS use of the eBLC and ACA Correlators was suggested. An AI for the Science IPT was set to study the scientific merit of such mode. It would be interesting to start a Discussion on this (BVV). Robert, Baltasar, Al, Todd and Darrel will explore the possibilities during next week's meetings.

Conway, Holdaway -- Configuration Group

  • The Technical specifications and SOW for the IFB for the AOS Road network design have been contracted. A contractor will be on the site 7 August to begin design. A design for road and fiber network at the high site is expected in September. Design of the extended array should occur during October-November.
  • New Configuration submitted for approval Passed CCB.
  • Y+ configuration now under design by Holdaway.
  • Proposed ACA Configuration approved.
  • ArrayCenter shows photos of the region of the center of the Array.
  • Please see the attached image, which has the roads Don sent me and the latest configuration I am working with. Several of these antenna locations were fixed since the visit to Chile. I am ignoring the antennas displaced from the roads on the north arm because there is nothing there which presents a problem. ALMA Y+ Array Extended configuration sites as of 2007 Jan 16.
    • Position 1: this has not been moved since the visit to Chile, but we don't have a road design to it.
    • Position 2: there was a road design to this spot in the very first roads M3 provided me like in September 2006. We need it, as otherwise there is a hole in the UV coverage at about 6km -- this antenna forms baselines with the cluster of antennas just about 6 km north on the North arm, and these baselines fill in the hole. Do we need this road? Yes, otherwise long after I've left NRAO, I'll be famous among users of ALMA's Y+ array for the "Holdaway Hole", and I don't want that.
    • Position 3: I don't know where the road went for this one, I thought we had a road there before.
    • Position 4: I thought we had made provisions for a road down here while we were in Chile.

Jeff Mangum -- Calibration

  • Calibration Plan: Current version of the calibration plan and associated documents ("examples", "roadmaps", "matrices", etc.) posted. Comments welcome.
  • Calibration Examples: The "meat" of the Calibration Plan. Review of these documents nearly complete.
  • Ancillary Calibration Devices: Documents which describe the weather station and temperature profile technical specifications have been developed. RFQ packets going out to vendors, with likely responses by end of January 2007. NOTE: I need suggested vendors for the temperature profiler.

Robert Lucas -- SSR

Michiel Hogerheijde -- DRSP

  • I am nearly complete with getting a group of ~10 reviewers together from ASAC. Later this week I will post the DRSP 2.0 projects on a secure website, along those projects from version 1.1 that remain unchanged or for which I have not received a response. The reviewers will each assess 5-10 projects, and communicate their findings directly to the authors. This also includes the projects for which no response was received, to double check that they indeed remain valid as-is.

  • This process will be completed by February 15. The authors will then have 1 month for their replies. By April 1 I will post the DRSP 2.0 on the web along with derived statistics.

Robert Laing -- Commissioning and Science Verification

Mark Holdaway/Steve Myers, Reid -- Imaging

  • Solar Observing

L.-A. Nyman -- Site Characterization

Remijan, Markwick-Kemper -- ALMA Working Group on Spectral Line Frequencies

  • became active this week after setting up the database in Manchester and putting out some fires with the database (i.e. server crashing, etc.)
  • AJMK and TR now both have access to the Splatalogue database in Manchester.
  • The database mirror has been set up at NRAO-CV.
  • AJMK is working on the ~200 edits sent by TR for resolving the QNs in the database.
