  1. The VLBI stations are specified by their two-character IVS codes that can be found at http://ivscc.gsfc.nasa.gov/about/org/components/ns-list.html. For each radio source with elongation angle <15°, the number of successful observations is given. During each session, many other ICRF2 radio sources were observed for a better sky coverage, not included in this table.
