TABLE  RequiredMosaicTopLevel

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:
  • Primary key is (programmeID,setupID)
  • (programmeID) references Programme(programmeID)
