Proposed for Inclusion in EAS/SAS

This product is proposed for inclusion in the SAS: maybe

These products contain the segmentation map produced by the object detection and deblending steps. It could be useful to have them in the SAS in case scientist want to replicate the morphology and photometry calculations performed by MER.

Detailed Description of the Data Product

Map showing the connected pixels of the objects detected on the corresponding MER Detection Mosaic Product. The object id numbers in the segmentation map should coincide with the id numbers in the MER Final Catalog Product. This product is an output from the MER object detection and object deblending Processing Elements.

The main elements inside this product are:

  • FilterList: List of filters that were used to produce the segmentation map (normally VIS or NIR filters).

  • WCS: The segmentation map astrometric parameters (e.g., CTYPE1, CRVAL2, CRPIX1, CD1_1).

  • ImgSpatialFootprint: The segmentation map spatial footprint.

  • TileIndex: The MER tile index.

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

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

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

  • ConvolutionKernelStorage (optional): Element that links to a file containing the convolution kernel used during the source detection.

  • QualityParams: The segmentation map quality parameters.
