• BL CORR sub arrays: Most significant issues were resolved and final acceptance is planned for November or December depending on pressure form PI projects 2015
• ACA: HW and SW issues are currently under investigation. Dedicated mission planned for end of November 2015.
Software Releases (I)
• To allow sub-arrays, certain functionality was migrated to a layer which performs slightly worse in very limited cases
• Improvements were made to allow for better linear scaling of the autocorrelations
• Hardware and Software problems have prevented the completion of ACA acceptance
• Action plan has been defined (next slide)
ACA enhanced capabilities in Cycle 3
Recovery Mission Plan:
• Send both ACA Subsystem Scientist and ICT Group Lead to the OSF by Nov/Dec
• Create hot-line between OSF and NAOJ to get every technical support,
• and, Extensive test on AOS2-STE without any interaction with Science work.
ACA trouble shooting toward Cycle 3
AQUA
• Used daily for the QA0 process
• Support for QA2 is being developed, requires changes in the life-cycle of Observing Projects and support from the Pipeline
• Trending to be included later, requires efficient query of produced data
SnooPI
• Replaces the current “public view” of the Project Tracker
• To be delivered 2016/Q1
• Modern “Single Page” application with REST-ful back-end

Control
• Cycle 3 - focus was on stability, including increased robustness to hardware errors
• Cycle 4 will be delivered for testing in December (including portion for solar observing)
• Emphasis on reducing the bug backlog, which should also help addressing operational reliability
Correlator
• Correlator - delivered, commissioning team recommended acceptance
• Will continue with sub-arrays, any high-impact bugs found will be addressed at a high priority vs. other correlator bugs
Control
• Dynamic Scheduling Algorithm and What To Observe tools were run in parallel in the second half of Cycle 2 – list of enhancements were generated and prioritized
• Important enhancements were implemented - DSA is on track for being used in Cycle 3
• ICT and ISOpT collaborating to improve usability of Scheduling for Astronomers on Duty

Pipeline
The Atacama Large Millimeter/submillimeter Array (ALMA), an international astronomy facility, is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. ALMA is funded in Europe by the European Organization for Astronomical Research in the Southern Hemisphere (ESO), in North America by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada (NRC) and the National Science Council of Taiwan (NSC) and in East Asia by the National Institutes of Natural Sciences (NINS) of Japan in cooperation with the Academia Sinica (AS) in Taiwan. ALMA construction and operations are led on behalf of Europe by ESO, on behalf of North America by the National Radio Astronomy Observatory (NRAO), which is managed by Associated Universities, Inc. (AUI) and on behalf of East Asia by the National Astronomical Observatory of Japan (NAOJ). The Joint ALMA Observatory (JAO) provides the unified leadership and management of the construction, commissioning and operation of ALMA.
