17 ANASAC Meeting – May 20, 2015 At increased ES observing frequency and efficiencies, Data reduction is straining resources at the ARCs – JAO is streamlining processes – NA is hiring more staff While TP observing has begun, TP data reduction path has still not been proven and distributed to ARCs No group-level data combination has been performed; “best practices” not established – NAASC is doing this individually via helpdesk & in- person visits (6 cases). About to roll out a CASAguide Cycle 1 & 2 Status: Challenges

19 ANASAC Meeting – May 20, 2015 ALMA Proposal Cycles Cycle 0: Sep 2011-Dec 2012 (990 proposals, 500h) Cycle 1: Jan 2013-May 2014 (1131 proposals, 800h) ~300 hrs transferred into Cycle 2 Cycle 2: Jun 2014-Oct 2015 (1382 proposals, 1700 h) Cycle 3 – Deadline was April 23 PRP meetings: June 22-26, 2015 (in Osaka, JP) Communication of Outcome of Review Process: August 2015 Start of Cycle 3: October 1, 2015 – Start of yearly cycles

20 ANASAC Meeting – May 20, 2015 Cycle 3 Proposal Process Improvements Several improvements were made to assist investigators – Cycle 3 Array schedule published in Proposers Guide – Document improvements Better explanations of multiple pointing and multiple tuning choices Improved calibration chapter in the Technical Handbook – Helpdesk and Knowledgebase “Cycle 3 News” top-level menu item on SP points to KB article that accumulates known issues Included graphics for some KB articles Helpdesk staffed for entire week prior to deadline, and 72h of continuous “follow-the-sun” emergency department (twice that of Cycle 2) – Questionnaire released much sooner, closing end May 340 replies to date

22 ANASAC Meeting – May 20, 2015

23 ANASAC Meeting – May 20, 2015 Cycle 3 Observing Capabilities and Policies Cycle 3 begins 1 October. Cycle 3 is no longer Best Efforts for standard proposals – New category: Non-standard = Bands 8, 9 10 or baselines > 2.5 km With Cycle 3, ALMA begins a 12 month proposal cycle Supplement to C (filler) projects: low frequency and under-subscribed LST ranges Capabilities for Cycle 3 (new / extended capabilities marked in red): – At least thirty-six 12-m antennas in the main array, and ten 7-m antennas and two 12-m antennas (for single-dish maps) in the ACA. – Receiver bands 3, 4, 6, 7, 8, 9, & 10 (wavelengths of about 3.1, 2.1, 1.3, 0.87, 0.74, 0.44, and 0.35 mm, respectively). – Baselines up to 2 km for Bands 8, 9 and 10. – Baselines up to 5 km for Band 7. – Baselines up to 10 km for Bands 3, 4, & 6. – Both single field interferometry and mosaics. – Spectral-line observations with all Arrays and continuum observations with the 12-m Array and the 7-m Array. TP Array use is limited to spectral line observations in Bands 3 to 8. – Polarization (on-axis, continuum in Band 3, 6 and 7, no spectral line, no ACA, no mosaics, no circular polarization). – Mixed correlator modes (both high and low frequency resolution in the same observation). – The maximum observing time per proposal, as estimated by the OT, is 100 hours.
