Table 3.
Definition of the parameters used in the decision tree for “M” sources (i.e. PYBDSF sources fitted with multiple Gaussians) in Fig. 6.
| Parameter | Definition |
|---|---|
| Source LR | LRsource > 0.639 |
| Any Gaussian LR | At least one Gaussian component has LRgauss > 0.639 |
| High source LR | LRsource > 6.39 |
| N Gaussian LR | N Gaussian components have LRgauss > 0.639 |
| Same as source | The ID(s) for the Gaussian component(s) are identical to the ID for the source |
| Source LR much better | LRsource > 10 & LRgauss < 10 & LRsource > 10LRgauss |
| Gaussian LR better | LRgauss > 10 & LRsource < 10 & LRgauss > 10LRsource |
| Same LR much better | LRsource > 100 & LRgauss(same) > 5LRgauss(different) |
| Widely separated Gaussians | Maximum separation between Gaussian components of the PYBDSF source larger than 15″ |
| Large neighbour | Large (> 10″) neighbour within 100″ |
| High LR for small Gaussians | LRgauss > 6.39 & the Gaussian size is < 10″ |
