Catalogued and multi-wavelength counterparts to STONKS X-ray alert sources per their alert classes.
| Alert class | No. | SIMBAD | Opt. | NIR | MIR | Opt & NIR | Opt & MIR | NIR & MIR | Opt, NIR & MIR | None |
|---|---|---|---|---|---|---|---|---|---|---|
| All | 70 | 25 | 40 | 40 | 16 | 31 | 14 | 15 | 13 | 21 |
| First det. | 23 | 4 | 11 | 8 | 3 | 5 | 1 | 3 | 1 | 9 |
| High flux | 27 | 10 | 11 | 13 | 4 | 9 | 3 | 4 | 3 | 12 |

Notes. The SIMBAD column indicates those sources which have SIMBAD counterparts as per the STONKS pipeline, but does not consider the quality of the association. The Opt., NIR, and MIR columns lists those sources with Gaia, 2MASS, or AllWISE counterparts. The last five columns list the numbers of sources with combinations of these counterparts.
