A Processing Block is an atomic unit of data processing for the purpose of SDP’s internal scheduler. Each PB references a processing script and together with the associated execution block provides all parameters necessary to carry out scheduling - both on TM’s side for observation planning and on SDP’s side - as well as enable processing to locate all required inputs once it is in progress. PBs are used for both real-time and deferred, batch, processing. An execution block will often contain many Processing Blocks, for example for ingest, self-calibration and Data Product preparation. |

A dependency between processing blocks means that one processing block requires something from the other processing block to run - typically an intermediate Data Product. This generally means that
As processing blocks might have many different outputs, the dependency “kind” can be used to specify how this dependency is meant to be interpreted (e.g. “visibilities”, “calibration”…) |
