The VLBA Calibrator List

The VLBA Calibrators List drives a search engine for finding calibrators which are close to a specified position. Please fill out the VLBA Calibrators Search Form below. The search will return a table of sources within the search radius, a diagram showing the proximity of each source to the search center, and plots of the sources visibility and image distributions.

The catalogs used in the Calibrators list were generated from observations and reductions by the NASA GSFC VLBI group, the NRAO and the USNO. More detailed information can be found from:
