Calibration Data

Standard calibration data are observations of calibrators needed to perform the correct calibration of the scientific data. They include the flux, bandpass, amplitude, phase and polarization observations taken during PI observations. This definition extends to data that are resultant from the Accurate Position Service (see Section 5.1).

All standard calibration data have no proprietary period even if they are the result of PI observations. However, there does not yet exist a mode independent of the Archive Access Tool to acquire calibration data that is associated with proprietary data. In the future, the Observatory may make such data accessible separately from the Archive Access Tool. If the Accurate Position Service (Section 5.1) is leveraged, the results will be public domain immediately and source positions, and in many cases, even images will appear on the geodetic web sites.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.
