Key criteria and definitions used in the decision blocks of the decision tree in Fig. 4.
| Parameter | Definition |
|---|---|
| Large | PYBDSF major axis >15′′ |
| Clustered | Distance to fourth nearest neighbour <45′′ |
| S | “Simple” source: single Gaussian PYBDSF source (and only source in the island) |
| LR | LR > LRth |
| High source LR | LRsource > 10 × LRth |
| Compact & high LR | PYBDSF source major axis <10′′ and LRsource > 10 × LRth |
| Same as source | The ID(s) for the Gaussian component(s) is identical to ID for the source |
| Any Gaussian LR | At least one Gaussian component with LRgauss > LRth |
| >1 Gaussian LR | More than 1 Gaussian with LRgauss > LRth |
| >1 Gaussian with high LR | More than 1 Gaussian with LRgauss > 10 × LRth |
| Compact Gaussian with high LR | Gaussian major axis <10′′ and LRgauss > 10 × LRth |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
