Notes. Columns are: 1. Date of the observation; 2. Instrument name; 3. Velocity offset of the broad-line component with respect to the narrow lines; 4. Full width at half-maximum (FWHM) of the broad-line component; 5–6. Gauss-Hermite coefficients h3 and h4 for broad-line component (for the STIS, IDS and ESI (2023) datasets we provide h5 and h6 values in a separate row); 7. Flux in broad Hα component; 8. Luminosity of broad-line component and 9. Virial estimate of the black hole mass from the Hα broad component using relation from Reines et al. (2013). For the Binospec dataset in the last row we also provide a MBH estimate from the spatial-spectral modeling of broad-line component.
