The VLA supports absentee VLBI observations, whether conducted during, or outside of, a Global Network session. Queries from an absentee observer concerning a specfic project should be directed to the AOC contact assigned to that project (see Section 3.16). VLA schedule file preparation assistance is provided by the data analysts (see Section 4.3). Absentee observers must provide the data analysts with all necessary scheduling information. For a Network project, this information is due at least two weeks before the start of the appropriate Network session. For a non-Network project, this information is due by the schedule file due date assigned by the VLBA scheduler.
Although VLA Operations fully supports absentee VLBI observing, visits by observers are welcomed and are especially encouraged if the observations are in any way atypical. Included in this category are VLBI spectral line projects regardless of recording format, and any phased-array VLBI projects for which radio frequency interference is expected.
