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)

Name Type Length Unit Description Default Value Unified Content Descriptor

programmeID int 4 the unique programme ID meta.id

setupID int 4 the unique setup ID. Probably one per programme, but just in case meta.id;meta.main

name varchar 64 Name of the mosaiced product set up ??

description varchar 256 Description of the set of mosaics ??

xExtent real 4 degrees The angular extent of the mosaic image in the x-direction ??

yExtent real 4 degrees The angular extent of the mosaic image in the y-direction ??

xOverlap real 4 degrees The overlap between adjacent mosaics in the x-direction ??

yOverlap real 4 degrees The overlap between adjacent mosaics in the y-direction ??

orientation real 4 deg Orientation of image x-axis to N-S. If default, use natural orientation of input images. -0.9999995e9

pixelSize real 4 arcsec The final pixel size of the mosaic -0.9999995e9 ??

zeropoint real 4 Zeropoint of each product -0.9999995e9

zpSystem varchar 8 System of zeropoint (Vega/AB) 'NONE'

backAlgo varchar 16 Algorithm/code used for background subtraction

mosaicSoft varchar 16 Mosaicing software (typically SWARP)

convSegm varchar 16 Convolution segmentation software

extractor varchar 16 Extraction software (e.g. SExtractor)

paramTemplate varchar 32 Template file for SWARP parameters

isExternal tinyint 1 Are mosaics produced externally (1), from external inputs (2) or all internal (0)

useStandard tinyint 1 Reprocess standard products as swarp mosaics (e.g. tiles) 0
