Sou323 ICRF reference sample (Liu+, 2017)

With the coordinate time series over 30yr, some of ICRF2 defining appear to be unstable and not suitable for defining a celestial frame. We have applied an improved selection scheme to pick out suitable sources as candidates. Finally, two sets of sources that show improved axial stability and sky distribution are recommended (Sou323 and Sou294). Only Sou323 is available.
