Emerson/Laing/Vila-Vilaro -- Instrument Scientists

Conway, Holdaway -- Configuration Group

  • The Technical specifications and SOW for the IFB for the AOS Road network design have been completed. A design for road and fiber network at the high site is to be bid for construction shortly. Design of the extended array is complete; bids for antenna pad construction are out.
  • Final configuration design. We continue to assess performance (see imaging, below). Tony will set up an independent group to assess configuration performance.
  • New <4km Configuration submitted for approval Passed CCB.
  • Proposed ACA Configuration approved.
  • ArrayCenter shows photos of the region of the center of the Array.

Jeff Mangum -- Calibration

  • Semi-transparent Vane Report has been received.
  • Pointing Design document now drafted.
  • 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, some need updates.
  • Ancillary Calibration Devices: Documents which describe the weather station and temperature profile technical specifications have been developed. Initial purchase documentation for (P,T,RH,Ws,Wdir) measurement devices sent to Robert Laing. NOTE: I need suggested vendors for the temperature profiler.

Robert Lucas -- SSR

  • Latest SSR meeting (2007-05-09); June meeting cancelled due to time conflict with Computing Leads meeting; no July meeting while group leader recharges his batteries.
  • Critical Design Review 5 occurred in May. Generally successful. See ASAC Charge.
  • Computing IPT subsystem leads met in Socorro last month.
    • New ATF 'csar' Jeff Kern, leads a team dedicated to 24/7 ATF support (but some effort diverted from development).
    • Integration/testing of Single Dish in July/Aug at ATF
    • Integration/testing of interferometry starting also : September; continued until ATF stops.
    • Many implementation details discussed and clarified.
  • WVR software meeting in Grenoble currently (TelCal)
  • ASDM changes being implemented/integrated. Freezout intended for end of year.

Michiel Hogerheijde -- DRSP See ASAC presentation on this subject, linked above.

  • All DRSP2.0 projects have now been reviewed and response of the authors is requested by Friday April 20. On April 17 a preliminary analysis was discussed by ESAC. The main conclusions were
    • Out of 149 projects from 53 authors, 42 were revised w.r.t. DRSP 1.0; 18 are entirely new; and the reminder (85) was either unchanged or no response was received (but still reviewed).
    • The distribution over science areas has not changed much.
    • Integration times were tweaked here and there, but the main uncertainty lies in including realistic overheads.
    • Quite a few projects requested cross-correlation of the 7m ACA antennas with the baseline-ALMA 12m antennas. While for some projects this is indeed essential, for most this was used only to increase the sensitivity. In terms of scheduling and operations this may be undesirable, and this needs to be reflected in the DRSP to make sure the 7m*12m is not 'overbooked'. How do we want to do the bookkeeping on the 7m*12m requests?
    • Details of the DRSP 2.0 still need to be entered into a spreadsheet, and a tally will be made of requested bandwidths / spectral resolution settings for later translation into correlator modes. OT is almost ready to try this out using DRSP 2.0 projects.
  • Hogerheijde presentation on DRSP2.0 to the ASAC

Once the response of the authors is in, the DRSP2.0 will go on-line without password protection.

Robert Laing -- Commissioning and Science Verification

Mark Holdaway/Steve Myers, Reid -- Imaging

  • CASA Simulator Report

  • Pointing selfcalibration for mosaics

L.-A. Nyman -- Site Characterization

  • The weather station 50-100m north of the APEX antenna was removed to the OSF. Its mounting pole was also removed.
  • The battery bank ESO2 now supplying power at the AOS will be moved to the guardhouse at the intersection of CH23 and the ALMA Road. Ulf Kaberger to implement; presumed done now but no confirmation has been received.

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.
