Detailed description of the data product

This product is the result of applying the MER Background Subtraction Processing Element to a MER Mosaic Product.

The main elements inside this product are:

• Instrument: The instrument name (VIS, NIR, DECAM, LSSTCAM) and the telescope name (Euclid, NOAO, LSST).

• Filter: The filter name (e.g., VIS, NIR_Y, NIR_J, NIR_H, DECAM_g, LSST_u).

• 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.

• BackgroundStorage: Element that links to a FITS file containing the subtracted background model.

• FilterTransmissionStorage (optional): Element that links to a FITS file containing the filter transmission data set.

• QualityParams: The mosaic image quality parameters.

• BackgroundQualityParams: The mosaic background quality parameters.

• ProcessingSteps (optional): Information about the processing steps associated with the background subtraction process.
