| Contains details of default stack image products curated in the archive. |
| This table contains details of all the default image stack products that are curated within the archive as part of the requirements for a particular survey. For example, the UKIDSS UDS is a deep stacked survey. The stacking curation task implemented within the archive uses the information in this table to produce the required stack(s) for a given programme when invoked as part of archive operations. Required constraints:
