The VLBA Calibrator List
!! ATTENTION !!
This search tool will receive limited support beginning 2022-08-15, and will be retired 2023-01-01.
The new VLBA Calibrator Search Tool is now the primary tool for identifying calibraotrs for VLBA ovbservations.
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:
