Notes. ^(a)NIRSpec ID. ^(b)Full Width Half Maximum of Hα (or Hβ), corrected for instrumental broadening (which is however negligible for the broad component). ^(c)Difference between BIC for the fitting without a broad component and with a broad component. ^(d)These cases are marked as ‘tentative’ in terms of the BLR detection, as ΔBIC < 10, the broad-line component is still significant at > 5σ.
