Notes: The columns show the (1) ID number, (2) FWHM in km/s, (3) line dispersion (square root of the second moment of the line profile or σ) in km/s, (4) the corrected redshift based on the velocity offset of Hα with respect to its theoretical central wavelength, z_corr, (5) integrated Hα flux in ergs cm⁻² s⁻¹, (6) the number of Gaussian components used to fit the Hα line profile, (7) single-epoch BH mass estimate using Eqn. 6 of Woo et al. (2015), and (8) bolometric luminosity using the bolometric correction from Trakhtenbrot et al. (2017) to convert the λL_λ(5100 Å) to L_bol. For ID#1-5 that were observed with the K_s filter, the λL_λ(5100 Å) were estimated from their Hα luminosity using Eqn. 4 of Woo et al. (2015), and the typical error of their log₁₀L_bol is ∼ 0.25. For the rest of the targets that were observed with the GRF filter, the λL_λ(5100 Å) were measured via Monte Carlo analysis of best-fit continuum after 1000 instances of fitting, and the typical error of their log₁₀L_bol is ∼ 0.014.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
