| Abstract: |
Cross-matching radio is different from that in the
optical. Radio sources can have multiple corresponding detections, the
core and its lobes, which makes identification and cross-identification
to other catalogs much more difficult. Traditionally, these cases have
been handled manually, with researchers looking at the possible
candidates; this will not be possible for the upcoming radio
ultimately leading to the Square Kilometer Array. We present a
probabilistic method that can automatically associate radio sources by
explicitly modeling their morphology. Our preliminary results based on a
simple straight-line model seem to be on par with the manual
associations. |
