Detailed description of the data product

An XML data product containing a FITS segmentation image - i.e. an image containing integer pixel values where pixels of a certain value correspond to a single source. This is used for object identification. These maps were created in MER, but in SHE_MER we reproject several MER tiles to the original VIS image projections for use in various internal SHE processes. The object id numbers in the segmentation map should coincide with the id numbers in the object catalogs.
