We generally associate detections with Object objects, within a given radius (which is a configurable parameter but generally is 1-2 arcsec).
We are working under the assumption that there is never going to be, within that radius, more than one source in the same image.
I don't know if this is necessarily a good assumption, as it depends on the source detection algorithm.
Usually this won't be a problem because the search radius is on the order of the PSF width, so it should never come up. But we should enforce this at some stage, maybe at the source detection time?
