| Contains details of default mosaic image products curated in the archive. |
| This table contains details of all the default image mosaic products that are curated within the archive as part of the requirements for a particular survey. A mosaic may be made from single exposure images or from stacks. For example, the UKIDSS UDS/DXS are deep stacked and mosaiced surveys. The stacking curation task implemented within the archive uses the information in this table to produce the required mosaics(s) for a given programme when invoked as part of archive operations. Required constraints:
