| describes each bundle of matching objects from different runs |
| One distinguished object (the first one observed) is the head of a match bundle. Each match object points to its MatchHead and all objects with the same MatchHead form a bundle. The MatchHead describes the bundle, its center point (average RA, DEC), the variance of RA,DEC, and the counts of hits and misses in the bundle. |
