ICRF   (International Celestial Reference Frame)= (ICRS) = ICRF2 
 Write:<<ICRF  JHHMMSS.s+DDMMSS>>
 N:  212+396+109+3414+4536
Object:Extragalactic (Rad)  (SIMBAD class: Radio = Radio Source)
  Note:The IAU Working Group on Reference Frames has elaborated a    reference frame of 610 extragalactic radio-sources to be    recommended by the IAU in 1997 as the materialisation of the    barycentric J2000.0 International Celestial Reference    System (ICRS, see 1995A&A...303..604A).
    New designations have been given to the objects in the frame    following the recommendations of the IAU TG on Designations.
    The coordinates will be published by April 1997 in a publication    issued by the Working Group on Reference Frames.
