Documentation for data product element DpdMerSegmentationMap:

MER segmentation map. This map shows the connected pixels of the objects detected on the corresponding MER detection mosaic. The object id numbers in the segmentation map should coincide with the id numbers in the MER final catalog. This product is an output from the MER object detection and object deblending modules.

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 object catalog. 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 produce the segmentation map (normally VIS or NIR filters).

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

  • 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 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 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.

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