Details on Acronym:   IVS
   IVS (International VLBI Service) Write:<<IVS BHHMM+DDd>>
<<IVS BHHMM+DDA>> Object:(Rad)  (SIMBAD class: Radio = Radio-source) Note:Extragalactic radio-sources in the northern sky, used as VLBA calibrators.
IVS sources are also IERS sources.
See also VCS1 to VCS6 J2000 designation for IVS sources.

Since about 2010, the Radio Fundamental Catalog (http://astrogeo.org/rfc/) also maintains a list of IVS sources, that are not only calibrators.
