Calibrator Information

The NRAO VLBA calibrator survey is very useful to search for a continuum source which can be used as a reference source to carry out the delay, bandpass, and phase calibrations. The source list of this calibrator survey can be found at the following VLBA homepage,


http://www.vlba.nrao.edu/astro/calib/index.shtml.

For delay calibrations and bandpass calibrations, calibrators with 1 Jy or brighter are strongly recommended as listed in the VLBA fringe finder survey:

Interval of observing calibrator scans must be shorter than 1 hour to track the delay and delay rate in the correlation process.
