Left: Euler diagram displaying the overlap between the three LRD characteristic criteria: a broad Balmer line, a dominant point source component at rest-optical wavelengths, and a spectroscopic v-shaped continuum. Right: Histogram showing the composition of overlaps in the Euler diagram where only two of the three features are measured. We note that objects with a rest-optical point source and a v-shaped continuum are 80% likely to have a broad line. In fact, in the remaining 20% we cannot reject a broad line, but our quality cuts restrict us from being fully confident. This suggests an underpinning physical link between the three LRD features.
