Astrometric classification of 647 VLBI sources
Listed in IVOA Registry (Virtual Observatory)
We present the result of our Allan standard deviation based classification according to their astrometric stability.
Description
The classification is divided into three categories (stable sources, intermediate sources, unstable sources). Stability of sources is qualified by the astrometric behavior of the source.
This determines in which category the source falls into. Then, stability of the source is also quantified by a stability index (two are proposed in the table). Those indexes enable to order sources in each category of the classification.
