ALMAGAL processing workflow. Schematic description of the five major steps. The process starts with “calibration and data staging”, preparing the data for the following steps (Sect. 4.1). We then determine line-free frequency ranges for the continuum emission, and generate a first set of images for each source and individual array (Sect. 4.2). The next step applies an automatized self-calibration process to each source and individual array (Sect. 4.3). The self-calibrated data of each array are then joint-deconvolved together to produce final images of continuum emission and line cubes (Sect. 4.4). Finally, the data products are quality assessed and stored for distribution to the consortium (Sect. 4.5).
