ADC_Keywords: Galaxies, Seyfert ; Surveys Keywords: galaxies: active - methods: statistical - catalogs - surveys Abstract: Using the most recent (April 2003) version of the VLA FIRST survey radio catalog (Cat. VIII/71), we have searched for radio emission from >2800 AGN taken from the most recent (2001) version of the Veron-Cetty and Veron AGN catalog (Cat. VII/224, superseded by 2003, Cat. VII/235). These AGN lie in the ∼9033 square degrees of sky already covered by the VLA FIRST survey. Our work has resulted in positive detection of radio emission from 775 AGN of which 214 are new detections at radio wavelengths. File Summary:

Note (1): As listed in Veron-Cetty and Veron, 2001A&A...374...92V, Cat. VII/224 (superseded by VII/235) The classification of the object is: S1 : Seyfert 1 spectrum S1h: broad polarized Balmer lines detected S1i: broad Paschen lines observed in the infrared S1n: narrow-line Seyfert 1 S1.0, S1.2, S1.5, S1.8, S1.9: intermediate Seyfert galaxies S2 : Seyfert 2 spectrum S3 : Seyfert 3 or liner S3b: Seyfert 3 or liner with broad Balmer lines S3h: Seyfert 3 or liner with broad polarized Balmer lines detected S : unclassified Seyfert S? : possibly a Seyfert H2 : nuclear HII region HP : high optical polarization (>3%) Note (2): A * in front of the redshift means that it has been estimated from a low dispersion slitless spectrum and is of lesser accuracy. Note (3): Where V magnitudes are not available other magnitudes are listed. These include Photographic (*), red (R), photographic O- or J- plates (O) Note (4): In table3.dat only
