The convention for numbering radio sources adopted by the IAU uses the 1950 coordinates of right ascension in hours and minutes, followed by the declination truncated to tenths of a degree. It was designed for a growing population of sources so that new sources may be added and given an IAU number, unlike, for example, the listing in the BD catalogue which is a closed assembly.
