11 ANASAC Meeting – May 20, 2015ALMA Board meeting at SCO 11

Prediction of Completion

• As of March 11: 1355 hrs of 2200 hrs remain– ~325 hrs observed ES blocks 17-21– 13 ES block remain ~ 800 hrs (~60hr QA0 pass

per block)– Implies 230 hrs unobserved => ~90% completion

• However:– Some projects simply cannot be scheduled due to

inability to do high frequency observations (> band 7) during the day• Compact configurations, LST~0h – 5h

• Extended configurations, LST~5h – 10h

– Other projects are in oversubscribed LSTs

Prediction of Completion (best case)L. Nyman, March 11

• Cycle 1: 16 projects unlikely to be observed (52 h)– 92% completion rate

• Cycle 2: 32 projects unlikely to be observed (121 h) – 91% completion rate

• Total: 48 projects unlikely to be observed (173 h)– 91% completion rate

• Most likely 4 Cycle 2 grade A projects will be transferred to Cycle 3

Executive Balance – Cycle 1(as of Feb/Mar Engineering time)

Regional Share: 33.8% 33.8% 22.5% 10.0% (<5%)✓


• 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 3 RESULTS


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


Cycle 3 Proposal ProcessImprovementsSeveral 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


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.


Proposal Submission for Cycle 3

1612 Proposal codes were assigned by the deadline on April 23, 2015 from around the world


Helpdesk Support• More complete coverage in week up to deadline• 365 tickets in total (178=49% for NA)

25


Cycle 3 Proposal Submission

• 1582 unique proposals (+14%) requesting 9037 hrs on the 12-m Array – 5.7 hrs per proposal– Oversubscription by hours = 4.3– 76% / 24% hrs requested “standard” / “non-

standard”• 1122 individual PIs and 3608 PI+Co-Is from 47

countries


Cycle 3 Proposal Statistics


Proposal ProcessFuture improvements

• Improvements to KB articles, including graphics• Revision of Primer and “Did You Know” flyer to include updated

and more accessible example observations• Videos to explain some of the more complex setups• More information on use of simulators with more examples

Starting the Cycle 4 planning earlier in the cycle if the data reduction schedule allows
