The VLBA Calibrator List is accessed via a search engine that locates calibrators near a specified celestial position. The VLBA data calibration pipeline is running selected data through an automated AIPS process that provides a best effort apriori calibration.The VLBA polarization calibration program calibrates the polarization electric vector position angle for a network of sources suitable for observing compact sources. |
