Schematic representation of the NGVS data flow. Quality control and preprocessing of raw data is performed at CFHT using two separate pipelines: the standard MegaPrime pipeline Elixir and Elixir-LSB, designed to take advantage of the NGVS step-dither observing strategy (see Section 3.5). Astrometric, photometric calibration, and stacking of Elixir frames are performed using three independent pipelines, MegaPipe, TERAPIX (in progress, and shown by the dashed lines), and THELI. Astrometric, photometric calibration, and stacking of Elixir-LSB frames are performed using MegaPipe and TERAPIX (see Section 4.2 for details). All data, from raw frames to final calibrations and data products, are stored at the CADC.
