Numbers of sources classified in each category by each different classification method.
| Diagnostic | Number classified in that category | |||
|---|---|---|---|---|
| method | (number with overall class of radio AGN) |

| AGN | SF | Intermediate | Unclassified | |
| D4000 vs. | 703 | 8392 | 1510 | 10 |
| L150 MHz/M* | (703) | (97) | (1318) | (3) |

| L150 MHz | (659) | (532) | (753) | (177) |

| W2–W3 | (1426) | (105) | (0) | (590) |
Notes. “AGN” and “SF” are (radio) AGN and star-forming classifications, respectively. “Intermediate” are the intermediate classifications for the D4000 vs. L150 MHz/M* or LHα vs. Lrad diagnotics; “unclassified” sources lack data for classification on that diagnostic. The bracketed number on the second row for each diagnostic shows the number of these sources that end up with an overall classification of “radio AGN” (with the rest classified as star-forming, which may include radio-quiet AGN). This can therefore be used to gauge the importance of each diagnostic in the overall classification. For example, the majority of objects classified as “AGN” by the BPT diagnostic are ultimately deemed to be radio-quiet AGN so this classification is not given much weight, although classification as “SF” by the same diagnostic is almost invariably secure.
