Data Product Types

The following tables contain lists of all data product types, as given by their file name suffix. There is one table per stage of processing. All tables indicate whether the file naming is exposure-based (Exp) or source-based (Src). When the product is not created by default, the flag Optional is indicated in the description. The different stages of the calibration pipeline are as defined in the Algorithms Documentation. The product name suffixes are active links to detailed descriptions in the following sections.
