VLBI sources in optical and radio

Presented by Mr. César GATTANO on 14 Mar 2016 from 17:00 to 18:00
Type: Poster Presentation
Session: Poster4-6
Track: 5: Geodetic and Astrometric VLBI Results
Board #: S5P6


Until now, the main criteria for selecting geodetic sources were based on astrometric stability and structure at 8 GHz [Fey et al., 2015]. Other physical characteristics, especially at other wave-lengths, including the optical, should also enter the selection procedure. To this aim, we propose to summarize all known physical caracteristics, thanks to the use of three different catalogs : the Large Quasar Astrometric Catalogue [Souchay et. al., 2015], the Radio Fundamental Catalogue (Petrov, http ://astrogeo.org/rfc/) and the Optical Characteristics of Astrometric Radio Sources [Malkin, 2013]. We also bring radio stability criteria derived from our own VLBI analysis. With such a compilation, we may identify new criterion for geodetic VLBI targets.
