Quasar UV/X-ray relation luminosity distances are shorter than reverberation-measured radius-luminosity relation luminosity distances

We use measurements of 59/58 quasars (QSOs), over a redshift range $0.0041\le z\le 1.686$, to do a comparative study of the radius--luminosity ($R-L$) and X-ray$-$UV luminosity…
