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. 1998AJ....116..516M: 1st ref. with ICRF objects. See also IERS. |
