Notes. Column (1) is RMID: correspondence with SDSS identifier can be found in Table 1 of Grier et al. (2017b). Column (2) is redshift. Column (3) is range of dates (MJD) for which the time-series analysis was undertaken. Column (4) is the Hα lag relative to the continuum. Column (5) is the luminosity of the Hα line. Columns (6), (7), and (8) are the Hα line width, characterized by FWHM in the mean spectrum, line dispersion in the mean spectrunm, and line dispersion in the RMS spectrum, respectively, all in the rest frame of the source. Column (9) is the reverberation virial product for Hβ from Paper I.

References. Line widths and luminosities are from Wang et al. (2019).
