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
========================================
.. DetailedDescStart

Map showing the connected pixels of the objects detected on the corresponding
MER :ref:`MERDetectionMosaic`. 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
:term:`Processing Element`\s.

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.
