Data Archive System

The NRAO Data Archive System provides access to all publicly available VLA, VLBA, and GBT data. NRAO data that remains within its proprietary period can be accessed via the scientific team via password. Advanced search capability is available. A collection of VLA and VLBA images are also available for browsing and downloads.

Data Archive Policy

All scientific data acquired withNRAO telescopes are stored in the Data Archive. Scientific data are reserved for the exclusive use of the observing team usually for 12 months after a project's final observing session has been completed. In certain circumstances, the default proprietary period may be lengthened; some Rapid Response Science proposals have shorter proprietary periods.

Source Lists & Surveys

The folowing links provide quick access to source surveys conducted with the VLBA, sometimes using other VLBI telescopes. The VLBA calibrator survey and the USNO Radio Reference Frame Image Database are particularly useful for finding reference sources for phase-referencing observations.
