TL;DR: In this article , the authors present measurements of broad emission lines and virial estimates of supermassive black hole masses for a large sample of ultrahard X-ray-selected active galactic nuclei (AGNs) as part of the second data release of the BAT AGN Spectroscopic Survey (BASS/DR2).

TL;DR: The second catalog and data release of optical spectral line measurements and active galactic nucleus (AGN) demographics of the BAT AGN Spectroscopic Survey was presented in this article , which focuses on the Swift-BAT hard X-ray detected AGNs.
