VizieR Online Data Catalog: SDSS Seyfert 1.9 galaxies with Ha emission line fit (Chen, 2021)
Abstract
We select our Seyfert sources from Chen & Hwang (2019MNRAS.485.3402C). This sample includes 54694 Seyfert 2 galaxies and 745 Seyfert 1.9 galaxies with 0<z<0.2. Our sample criteria are a signal-to-noise ratio (S/N) of Hα>3, an S/N of [OIII]>5, and log L[OIII] [erg/s]>40.125. We obtain the optical spectra from the SDSS Data Release 10.
