Scaling Tests using Object Databases

“A region of the sky is digitized at two different wavelengths, yielding two sets of candidate bright objects, each characterised by a position (x,y) and width (sigma). The problem is to find which bright objects match in both sets, consistent with the width of each.”

Analogous to e.g. matching energy deposits in an r-? view of a calorimeter, and track impact positions.
