Cycle 1 & 2 Status: Challenges At increased ES observing frequency and efficiencies, Data reduceon is straining resources at the ARCs JAO is streamlining processes NA is hiring more staff While TP observing has begun, TP data reduceon path has sell not been proven and distributed to ARCs No group- level data combinaeon has been performed; best praceces not established NAASC is doing this individually via helpdesk & in- person visits (6 cases).

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. 23 ANASAC Meeting May 20, 2015
