Radio properties of NLS1 and BLS1 galaxies from the FIRST and the VLASS

Data files of Narrow-line Seyfert 1 (NLS1) galaxies and Broad-line Seyfert (BLS1) galaxies detected in the Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) and the Very Large Array Sky Survey (VLASS). The original NLS1 and BLS1 samples published by Paliya et al. (2024 MNRAS 527, 7055) was cross-matched with the FIRST catalog (Helfand et al., and the detected sources with the VLASS (Lacy et al., 2020 PASA 132, 035001) first and second epoch observations. Each zip file contains the dataset and its description in a ReadMe file.
