DetailedDescStart Mosaic used to perform the object detection. It could be a VIS :ref:`background-subtracted mosaic ` or a stack of the three NIR :ref:`background-subtracted mosaics `. This product is an output from the MER object detection :term:`Processing Element`. The main elements inside this product are: * **FilterList**: List of filters that were used produce to the detection mosaic (normally VIS or NIR filters). * **WCS**: The mosaic astrometric parameters (e.g., CTYPE1, CRVAL2, CRPIX1, CD1_1) * **ZeroPoint**: The photometric reference zero point to convert the image untis to AB-magnitudes. * **ImgSpatialFootprint**: The mosaic spatial footprint. * **TileIndex**: The MER tile index. * **PatchIdList**: The sky patch ids associated to the product. * **ObservationIdList**: List of unique IDs identifying the Euclid observations that were used to generate the product. * **CalblockIdList**: The calibration block ids associated to the product. * **CalblockVariantList**: The calibration block variants associated to the product. * **ProcessingMode**: The MER pipeline processing mode (e.g. WIDE, DEEP) used to generate the product. * **ReferenceObservationDateTime**: Reference observation date time for GAIA proper motion correction (only applicable to Euclid observations). * **FirstObservationDateTime**: Observation date time of the first Euclid observation used to generate the product. * **LastObservationDateTime**: Observation date time of the last Euclid observation used to generate the product. * :ref:`DataStorage `: Element that links to a FITS file containing the detection mosaic signal data set. * :ref:`RmsStorage `: Element that links to a FITS file containing the detection mosaic rms data set. * :ref:`FlagStorage `: Element that links to a FITS file containing the detection mosaic flag data set. * :ref:`PsfModelStorage `: Element that links to a FITS file containing the detection mosaic catalog PSF. * :ref:`QualityParams `: The detection mosaic image quality parameters. .. _mer-detection-mosaic-image-fits: Image FITS file ^^^^^^^^^^^^^^^ See the :ref:`MER background-subtracted mosaic image FITS file ` documentation for more details.
