Table pub.mgd.map_coordinate
A record in this table represents one Coordinate Map; a set of Coordinate Map Features of the specified Units for the specified Object. The Object can be an MGI object (Chromosome or Sequence), or a non-MGI object (in which case the _Object_key and _MGIType_key are null). A Coordinate Map can belong to at most one Collection.
