Notes: The correlation Ra-Dc and the MJD of observation span are not available for the sources treated as arc sources. (1) ICRF Designations, constructed from J2000.0 coordinates with the format ICRF JHHMMSS.s+DDMMSS or ICRF JHHMMSS.s-DDMMSS They follow the recommendations of the IAU Task Group on Designations. (2) IERS Designations, constructed from B1950 coordinates. The complete format, including acronym and epoch, is IERS BHHMM+DDd or IERS BHHMM-DDd (3) X: Structure Index at X-band S: Structure Index at S-band H: Asterisk indicates that the source serves to link Hipparcos stellar reference frame to the ICRF. (4) Number of pairs of delay and delay rate observations. (5) A # indicates that the source is suspected to be not suitable to define the axes in the future.
