Detailed Description of the Data Product¶
This catalog contains all the sources from the SIM True Universe galaxy catalogs that overlap the inner core area of a given MER tile. This product is intended to be used as an input product for the MER analysis pipeline, in the case the main MER pipeline was run using simulated data.
The main elements inside this product are:
SpatialCoverage: The catalog spatial coverage.
SpectralCoverage: The catalog spectral coverage with a list of the filters that were used to produce the catalog (e.g., VIS, NIR_Y, NIR_J, NIR_H, DECAM_g, LSST_g).
TileIndex: The MER tile index.
PatchIdList (optional): The sky patch ids associated to the product.
ObservationIdList (optional): List of unique IDs identifying the Euclid observations that were used to generate the product.
CalblockIdList (optional): The calibration block ids associated to the product.
CalblockVariantList (optional): The calibration block variants associated to the product.
Release: The SIM True Universe galaxy catalog release version.
DataStorage: Element that links to a FITS file containing the catalog data set.
SIM galaxy catalog FITS file¶
This FITS file follows the same format as the SIM True Universe galaxy catalogs FITS files.
