Issue Date: | 2016 | Journal: | VizieR Online Data Catalog | First Page: | VII/274 | Abstract: | The Roma-BZCAT is now at the 5th Edition which contains coordinates and multi-frequency data of 3561 sources, about 30% more than in the 1st edition, either confirmed blazars or exhibiting characteristics close to this type of sources. With respect to the previous editions, this new edition has relevant changes in the sources' classification and has a new format for the notes in the tables. We emphasize that all the sources in the Roma-BZCAT have a detection in the radio band. Moreover, a complete spectroscopic information is published and could be accessed by us for all of them, with the exception of BL Lac candidates. Consequently, peculiar sources as the so called "radio quiet BL Lacs", which are reported in some other catalogues, are not included here because of possible contamination with hot stars and other extragalactic objects. | URI: | http://hdl.handle.net/20.500.12386/33994 | URL: | https://cdsarc.cds.unistra.fr/viz-bin/cat/VII/274 | Bibcode ADS: | 2016yCat.7274....0M | Fulltext: | open |
