The links below will provide information that a user may wish to access during VLBA observations, and also describe VLBA performance monitoring and post-observation access to ancillary data. Since most observations are dynamically scheduled, many observers will not know in advance when their observations take place. Data correlation usually occurs 3-6 weeks after an observation, using parameters specified in the original schedule file.
