Discussion Items

  1. NAASC (Jewell)
  • Transitions
    • It is a pleasure to welcome John Carpenter, who has accepted the Key International position of Observatory Scientist at the JAO, effective on or about 2015 September 21.
    • It is also a pleasure to congratulate Karin Oberg to the ASAC, where she will follow Dick Plambeck. We thank Dick for his service on the ASAC. Most recently he has served as liaison to the ADSC.
    • This will leave vacancies on the ANASAC; we welcome your suggestions for new members.
  • ANASAC f2f Meeting Report
  • The committee made recommendations & comments on the following areas. We will provide our preliminary response at this telecon and a formal response when the full Users’ Committee report (incorporating the ANASAC report) is received.
  • Prioritization
    • Data Reduction
    • Archive capabilities
    • EOC completion
  • Transparency
    • Decision process for observing capabilities
  • Integration of the ANASAC into the Users Committee
  • Charge 1 – Outcomes from Cycles 0, 1, 2 & Archive
    • Archive publication statistics

    • Recommendation to integrate the ANASAC into the selection process
  • Standing Charges 1 & 2 – Assisting ASAC in presenting a NA perspective; leadership in workshops
    • Request for an update on making NAASC computing resources available to the community
  • Standing Charge 3 – regarding broadening ALMA’s base within the community
    • User survey results
  • Standing Charge #4 – Evaluation of the Proposal Process (Cycle 3)
    • [Question for committee regarding strategy for proposing for prior projects that have not been observed by the time of the deadline]
  • ALMA Construction
    • Vertex Antenna Plan
  1. Program Scientist (Wootten)
    • July eNews copy for ALMA
      • Science portal for announcement of additional SV data on M100 (combining 12m array, ACA and TP data) and 3C238 (polarization) to be published at end of July.
      • The IRAS 16293 Band 4 dataset is currently being reduced in CASA 4.4 and the data reduction on 3c138 from the LBC is nearly complete. These two sets of data will be released after M100 and 3c286.
    • Right now on the array: It is EOC week. Software testing involving simultaneous subarrays is one focus, first tests of the Band 5 receiver is another.
      • Weather conditions last night: Wind speed: 5 - 15.0 [m/s], PWV: 0.6 - 1.1 [mm], Temperature: -8.0 - 13.0 [°C]
      • Average antennas used during the shift, by band and array family: Antennas at the AOS: (52x12m, 12x7m). Antennas available at the AOS: (46x12m, 12x7m). Approximate Array configuration: C34-6/7
    • ALMA Proposal Review process redux
      • User Survey for Cycle 3 proposal submission in hand. Very good response. Above 80% of PIs responded...going through results to summarize.
      • Status of ANASAC Proposal for (non-)rollover at end of Cycle – ANASAC expressed concern that for our yearly cycles there will always be 5mo of uncompleted observations at the time of the call. They suggested that we allow both A and B proposals to roll over 1 cycle. They argue that if we are observing correctly, then less than 10% should remain at the end of an observing season, so there should not be much queue-clogging from this. High frequency could be particularly impacted by yearly weather variations, so we could reserve the “B” grade for the not-as-highly-ranked high frequency observations (less than 15% of all submitted proposals) so these don’t clog the queue.
      • AEDM 2010-0780O (Rev3): AEDM_2010-078-O_(Rev3)_Principles_of_ALMA_Proposal_Review_Process (to be updated?)
    • DDT proposal response time (Osten)
    • Development: The deadline for submissions in response to the ALMA/NA Call for Development Studies issued in March was 12 June. 15 valid proposals were received from 56 proposers representing 20 institutions requesting a total of $2.528M; $1M is available. The proposals are now being distributed to referees as nominated by ANASAC. The funded studies are expected to begin on 1 October 2015.
    • AOS Artificial Source. - Status June 2015.
      • In Fall 2010 Richard Hills wrote a specifications document describing ideas for an Artificial Source to be placed on a tower on the AOS at a suitable location, with a number of possible uses for characterization of ALMA Components. That document is Requirements for an Artificial Source R. E. Hills. I provide the most recent copy I have, which is from Fall 2010.
      • Shortly thereafter Hitoshi Kiuchi, of NAOJ, began working on construction of an Artificial Source within the auspices of the NAOJ ALMA Development Program.
      • Hills had proposed a location on Chajnantor in his document. However, in Kiuchi’s investigation it was found that better lines of sight to antennas could be achieved from a site on Cerro Honar, located to the South of the Center of the Array. Over the development period (which continues) the device was constructed. A Presentation was made by Kiuchi at the 2013 February Development Workshop held in conjunction with the ASAC meeting held at that time in Mitaka. The presentation from that meeting is provided. In the meantime, Kiuchi-san has maintained an upgrade program for the device.
      • Some interest was expressed in the status and specifications of the transmitter at the May 20, 2015 ANASAC meeting. It was noted that the device would be very useful for characterizing some aspects of antenna performance at the AOS, potentially including surface holography and polarization beam mapping. It was also noted that the source would be extremely useful for tests associated with the ALMA Phasing Project now nearing completion. Wootten was given an Action Item to provide details. Daisuke Iono provided the Specs for As-built Artificial Source from Kiuchi-san. A tower at the site at Honar will host the source and an application for its operation has been filed with the Chilean radio frequency authorities.
      • Additional update from Stuartt Corder4 June 2015: To date, there were 3 activities required before the source could be installed, engaged and utilised at the defined location on Cerro Honar:
        1. Installation: The JAO has long had the action to install the physical connections for the artificial source. Recently it was discovered that the rework of the digital radio installation would provide ample opportunity to include, for small cost, additional installation to allow for function of the artificial source.
        2. Engagement: Due to changes in legislation over the development period, a permit will be required to turn on the device. Among other steps this requires official signatures from other facilities on the plateau as well as the Chilean Government. This process has been made more difficult by the transition in government and the current state of the relevant government body required for the permitting.
        3. Utilisation: ALMA software development is required to allow the ALMA delay server to send delays for a horizon source in a way that makes reasonable results.
      • All of these have been blocking until recently (1+3 have been simply because of conflicting priorities). SC has been treating item 2 as the main blocker because JAO has had other things to for those groups to work on and other projects to prepare as nothing can be done without the permit.
      • In May, the signatures from the other projects on the plateau were obtained and the permit now sits on the desk at the Chilean authorities. The timeline for approval is a bit unclear but for now it is simply a formality. In addition, it has been determined that adding some small scope to the radio upgrade work on Honar (to provide us with digital radio) will allow us to add the artificial source to the installation.
      • This is scheduled for execution during Q3/4CY2015. If this all goes according the plan, the online software team will be tasked at the Computing Planning Meeting # 5 (2015 December 1-3) to complete the relevant work. This would imply that the software implementation would be available in Q2CY2016 for initial testing and potential use in the Q2/3CY2016 timescale. There is also some potential use of the source available prior to full implementation of the online software improvements.
