All Tables

• Table 1: Number of quasars cross-identified between the recent catalog of Véron Cetty & Véron (2003) and the three categories of catalogs used in the construction of the ICRF: 212 defining sources, 294 candidate sources and 102 other sources. Two different angular thresholds have been chosen for the cross-identification: 2'' and 4''. The rms concern the difference in the positions, in arc-seconds, for the cross-identified sources.
• Table 2: Number of quasars cross-identified between the recent catalog of Véron Cetty & Véron (2003) and two categories of catalogs used in the construction of the ICRF: the combination of the defining, candidate and other sources of Table 1, with 608 sources, and its extension, the ICRF-Ext.2 catalog containing 717 sources. Two different angular thresholds have been chosen for the cross-identification: 2'' and 4''. The rms concern the differences in the positions, in arcsecond, for the cross-identified sources.
