VizieR Online Data Catalog: Multifrequency catalogue of blazars, Roma-BZCAT (Massaro+, 2009)
Abstract
The Roma-BZCAT is structured in two parts. Part 1, at present the only one available on-line, contains the lists of blazars, which are classified in three main groups, according to their spectral properties. Each blazar is identified by a three-letter code, where the first two are BZ for blazar and the third one specifies the type, followed by the truncated equatorial coordinates (J2000).
The codes are defined in the "Note (G1)" below. (2 data files).- Publication:
