1. All Versions of the VLBA OSS

The VLBA Observational Status Summary (OSS) is a comprehensive description of the VLBA instrument and typically is updated preceding each Call for Proposals.  The following table provides links to the versions appropriate to recent observing periods.

Only the current version, at the top of the table, is suitable for proposing and planning future VLBA observations.  Older versions are maintained to support scientific research based on archival VLBA observations.
