ALMAPipeline Status• ALMA Interferometric Pipeline is ready to support Cycle 1
Data reduction– Calibration and Diagnostic Images of Phase and
Bandpass Calibrators– Single Dish through imaging*– No support for combination– Some human intervention still required:
• Calibrator Fluxes• Extraordinary Flagging
• Rapid progress made in past year:– Tiger Team led by Todd Hunter– Built on experience from cycle-0 reduction
* Still developing global consensus on best single dish reduction. Pipeline is closely connected to this discussion.

ALMACycle-1 Operations • Early Cycle-1: Parallel Reduction
– Each ARC organized slightly differently– Pipeline and manual scripts will be run in parallel results
compared by reducer• Common feedback forms to pipeline to describe
meaningful differences from human reduction.• Late Cycle-1: Pipeline Calibration
– Pipeline does primary calibration for most projects• Band 9, special cases still needs manual reduction.• Data reducer starts with calibrated data from the
archive and does reference imaging.Actually had hoped to already be at this state by now!

ALMALooking Forward• Support for cycle-1 operations:
– Dealing with bugs (ours and theirs)• WebLog
– Meeting existing requirements from first focus group meeting
– Revisit WebLog requirements (Q1-2014) based on experience for Cycle 1
• Cycle-2 Capabilities
12
• More complicated SPW setups
• Initial Polarization Calibration
• Low SNR Cases (Band 9)
• [More] Flagging Heuristics• Science Target Imaging:
• Are we meeting targets.
Planning for user test prior to Cycle-2 Operations to gather responses from Cycle 1 Experience.
