Detailed description of the data product

Mosaic used to perform the object detection. It could be a combination of the VIS and NIR Background-subtracted Mosaic Products. This product is an output from the MER Object Detection Processing Element.

The main elements inside this product are:

  • FilterList: List of filters that were used produce the detection mosaic (normally VIS or NIR filters).

  • WCS: The mosaic astrometric parameters with linear (e.g., CTYPE1, CRVAL2, CRPIX1, CD1_1) and, optionally, non linear terms (PV1_0, PV2_0, …).

  • ZeroPoint: The photometric reference zero point in magnitude units.

  • ImgSpatialFootprint: The mosaic spatial footprint.

  • Masks (optional): Euclid bit masks present in the flag image data set.

  • TileIndex: The MER tile index.

  • PatchIdList (optional): The sky patch ids associated to the product.

  • ObservationIdList: List of unique IDs identifying the Euclid observations the were used to generate the product.

  • CalblockIdList (optional): The calibration block ids associated to the product.

  • ProcessingMode: The MER pipeline processing mode (WIDE or DEEP) used to generate the product.

  • DataStorage: Element that links to a FITS file containing the mosaic signal data set.

  • RmsStorage: Element that links to a FITS file containing the mosaic rms data set.

  • FlagStorage: Element that links to a FITS file containing the mosaic flag data set.

  • PsfModelStorage: Element that links to a FITS file containing the mosaic PSF model.

  • QualityParams: The mosaic image quality parameters.

  • ProcessingSteps (optional): Information about the processing steps associated with the production of the detection mosaic.
