The VLBA Calibrator List

!! ATTENTION !!
The new VLBA Calibrator Search Tool is now available as a beta version.
Users are encouraged to try the new tool and provide any feedback via the helpdesk.

The VLBA Calibrators List drives a search engine to find calibrators that 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 and a diagram showing the proximity of each source to the search center. Plots of the source visibility and image distributions are given for many sources.

This catalog contains the same source list that is in the NRAO VLBI SCHED program. More detailed information can be found from:
