Phase-Referencing Cycle Times
VLBA Scientific Memo No. 20

Jim Ulvestad

April 9, 1999

Abstract:

This memo gives phase-referencing switching times to be used by the VLBA, as calculated from equations given by Beasley and Conway. Estimates are given as a function of elevation angle for 8 wavelengths ranging from 7 mm to 21 cm, and for good, bad, and typical tropospheric conditions, always assuming a speed of 10 m stex2html_wrap_inline210 for the turbulence.



Connect with NRAO

The NSF National Radio Astronomy Observatory and NSF Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NSF NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NSF NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NSF 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. NSF NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The U.S. National Science Foundation (U.S. NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
