  • Topics:
    • Publication Progress with ALMA Cycle 0 and SV data choice-yes
    • Metrics to characterize the ALMA User Base Metrics NRAO will be using to evaluate if the NRAO is successfully reaching the broader, non-expert community choice-yes
      • Proposers to ALMA and to other NRAO telescopes
    • NRAO PR efforts and how PR efforts are coordinated with the other regions (Provided by C. Blue and J. Stoke) choice-yes
    • NRAO plans to keep the community informed on ALMA progress (i.e., how to improve the transparency of what is happening with ALMA) (Wootten: Portal, eNews, Direct Contact) choice-yes
  • ANASAC DISCUSSION: Is the publication rate reasonable, and if not, what is the bottleneck in publishing the data?
    • ASAC Charge #1: Assess the scientific outcomes and impact from Cycle 0. This should include some preliminary quantitative assessments, such as numbers of papers published and quantitative impact metrics, along with a qualitative assessment. Coordinate with the JAO and the regional ARCs, who would collect the necessary information.

10.30 – 10.45 Break

10.45 – 12:00 Cycle 1, Lead-in to Cycle 2 - Hibbard choice-yes

  • Topics
    • Report on Cycle 1 Status & Cycle 2 Preparations(company private - do not share)
      • Cycle 1 Status
      • Cycle 1 Results (Observing statistics, timescale for data reduction & delivery, Cycle 1 completion likelihood)
      • Cycle 2 (Basic Capabilities, Restrictions, Improved OT Features)
      • Cycle 2 Preparations (Official Documents, "Value Added" Material, OT tests)
  • JAO plan for long-term observing seasons (Deleted - get from EDM: AEDM 2013-043-O)
    • ASAC Charge 2 [ SUBJECT TO CHANGE ]: Assess the status of Cycle 1 observations and progress made towards the Cycle 2 call for proposals. For Cycle 1, are the data meeting user expectations, modulo the best efforts approach to early science? Are the data being released to the PIs in a timely fashion? For Cycle 2 preparations, is the OT keeping up with the capabilities of the array likely to be listed in the call? [Does the support from the ARCs continue to meet users' needs? - ADDRESSED BELOW]
    • Possibly new charge related to ALMA long-term observing cycle (TBC)
  • ADDITIONAL READING: All items are drafts.

12.00 – 13.00 Lunch.

12.45: Meet the NAASC choice-yes

13.00 - 13.30 Panel discussion session with NAASC choice-yes

13.30 – 14.00 Policy Issues - Jewell choice-yes

  • Topics
    • NRAO "Position paper" on PI "immediate access" to raw data: Originally written for ALMA Board, but given their attention to other matters it is suggested that the ALMA Directors Council should decide. This will impact what is written in the update to the Operations Plan to be drafted by the end of the year. Therefore, ANASAC should indicate to NRAO Director how strongly they support or disagree with this position
    • ALMA DRAFT Duplication policy: ASAC has agreed to this version (will replace what currently appears in the current draft of the Cycle 2 Proposers Guide)
  • ANASAC DISCUSSION: Discussion of above policies
    • ASAC Charge 3: With Cycle 0 and Cycle 1 proposal evaluation cycles completed, it is now of high importance to have a clear policy in place regarding the definition of duplicate observations for Cycle 2. The ASAC should work with the JAO and other interested parties to define what constitutes a "duplicate" observation.

14.00 – 14.45 Community Outreach - Remijan

14.45 – 15.15 Committee feedback session (Carpenter)

15.15 – 15.30 Break

15.30 – 16:00 Current North American Plan - Shannon, Randolph choice-yes

  • ANASAC-Development Presentation
  • Topics
    • Status of Current NA Studies and Projects
    • Proposal to roll out the ALMA Phasing Project (APP) capability (presented by Shep Doelman)

16.00 – 16:30 Future Projects - Wootten, Randolph, Shannon

  • Topics
    • Plans to evaluate the development studies and distribute the results (Wootten)
    • Plans to coordinate NA ALMA development studies/projects with the other regions (Wootten) choice-yes
    • ASAC Charge #4: The regional project scientists and the JAO will provide ASAC with materials, such as summaries, status updates, and other information of the completed and ongoing Development studies. ASAC should assess the scientific merit of these studies (e.g. discuss the uniquess for ALMA, the advantages and drawbacks of each capability, etc.), which will serve as a basis for further dialogue of the ALMA Development Plan.

16.30 – 17:00 Future Projects - Discussion

  • ANASAC DISCUSSION: Discussion of the long-term (10+ years) priorities for ALMA development and APP plan (Bolatto, Wootten)

09.00 – 10;30 CASA and ALMA Archive – Kern, Rawlings, Lacy choice-yes

  • Topics
    • CASA Presentation (Kern, with appearance by video)
    • ALMA Pipeline Presentation (status of the pipeline, what is delivered by the pipeline, testing status report from Remy)
    • Presentation on the archive; describe plans to assist users in reducing/analyzing increasingly larger data sets
  • ANASAC DISCUSSION: discuss what more may be needed to make the archive a useful entry point for beginners and for data miners
    • ASAC Charge #5: Comment on the utility of the archive and also the usefulness of current user software, such as CASA. How easy is it to access and use data from the archive? Are there critical functionalities missing from CASA? ASAC should also comment on data management plans for large data sets.

010.30 – 11:00 Regression Testing - Peck

  • No material available - JAO will present material to ASAC prior to their October f2f
    • ASAC Charge #6: Comment on a plan from the JAO to test the reproducibility through repeated observations of well characterized targets with a range of relevant properties.

11.00 – 11.15 Break

11:15 – 12.00 Discussion

  • ANASAC DISCUSSION: The deadline for ALMA proposals during full operations and timing relative to NSF AAG deadline
  • ANASAC DISCUSSION: In view of the large cycles anticipated for cycles 2 and 3, how do we keep the science timely? Do we want to encourage larger proposals before "full" operations start, and if so, how? Should we encourage more DDT?

12:00 - 13:00 Talk by Professor Satoshi Yamamoto from the Department of Physics at the University of Tokyo

  • Title: Carbon-Chain Molecules for Astrophysics
  • Abstract: One of characteristic features in chemical compositions of molecular clouds is existence of various carbon-chain molecules, such as HC2n+1N, CnH, CnH2, and CnS.. These highly saturated hydrocarbon molecules have preferentially been detected in young prestellar cores, while they are generally deficient in evolved prestellar cores and star-forming regions. On the other hand, NH3 and HN2+ become abundant in the evolved prestellar cores. Hence, the CCS/NH3 and CCS/HN2+ ratios, for instance, have been employed as a chemical evolutionary tracer of molecular cloud cores. In this talk, I am going to present the extension of such studies toward the following two directions. (1) Regional-to-region difference of a fraction of carbon-chain rich cores: We have studied the CCS/NH3 ratio toward many nearby dense cores. Carbon-chain rich cores are found in Taurus and Aquila lift, whereas they are absent in the Ophiuchus region. This seems to indicate that a timescale of the starless-core phase is different from region to region owing to environmental effects of each region. (2) Discovery of protostellar cores harboring rich carbon-chain molecules: Although carbon-chain molecules are generally deficient in star-forming regions, we found the protostellar cores with extraordinarily rich carbon-chain molecules. They are L1527 in Taurus and IRAS 15398-3359 in Lupus. In these sources, carbon-chain molecules are efficiently produced from CH4 evaporated from dust grains in a warm and dense region around the protostar (warm carbon-chain chemistry: WCCC). An origin of this peculiar chemistry is discussed in relation to past star-formation processes in these sources. Based on these two topics, I would like to demonstrate a novel aspect of carbon-chain molecules in star-formation studies.
