X-ray and optical luminosities for Chandra sources with Gaia counterparts. Arrows extending from mean luminosity to flare luminosity for flaring sources are shown. Lines of constant X-ray to optical luminosity ratios are shown. Sources discussed in Section 5 are labeled. This figure is available online as an interactive figure, with the ability to zoom, pan, and display detailed information for each source.

An interactive version of this figure is available in the online journal.
