| Contains a subset of the entries in Detection that are flagged as junk |
| Each set of plate detections in the SSA has been run through an automated junk detection algorithm (Storkey et al., 2003) to flag any objects that are a result of curvi-linear lines, circular or halo-type artifacts on the source photographic material. These junk identifications are done with a high degree of accuracy and attributes describing the junk detections are recorded in this table. |
