<DESCRIPTION>A unique number assigned to a group of catalogue entries which are assumed to be the same source. The process of grouping detections in to unique sources has changed since the 2XMM catalogue series and is described in Section 3.8 (https://xmmssc-www.star.le.ac.uk/Catalogue/3XMM-DR4/UserGuide_xmmcat.html#DiffUniqueId). The SRCID assignments in 4XMM-DR12 bear no relation to those in 3XMM-DR4 and earlier but the nearest unique sources from the 3XMM-DR4 catalogue to the 4XMM-DR12 unique source is provided via the DR4SRCID column.</DESCRIPTION>
