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

Cycle 1 & 2 Status: Challenges
• 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 & inperson visits (6 cases). About to roll out a CASAguide

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

Cycle 3 Observing Capabilities and Policies
•
•
Cycle 3 begins 1 October.
Cycle 3 is no longer Best Efforts for standard proposals
–
•
•
•
With Cycle 3, ALMA begins a 12 month proposal cycle
Supplement to C (filler) projects: low frequency and under-subscribed LST ranges

New category: Non-standard = Bands 8, 9 10 or baselines > 2.5 km
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.
