  1. ALMA Pipeline Progress and Status ANASAC Face-to-Face Sept 16-17, 2013 • Jeff Kern • CASA Team Lead

  2. Pipeline 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. ANASAC Face-to-Face: Sept. 16,17 2013

  3. Organization • Pipeline Working Group now formed Liz Humphries (Chair) Eric Villard (Deputy) Remy Indebetouw Hiroko Shinnaga Todd Hunter (ex officio: Tiger Team Lead) • International test / user team • NAASC Data Analysts • JAO Data Content Managers

  4. Cycle-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!

  12. Looking 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 • 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.
