The Third Vlba Calibrator Survey — Vcs3
This paper presents the third extension to the Very Large Baseline Array (VLBA) Calibrator Survey, containing 360 new sources not previously observed with very long baseline interferometry (VLBI). The survey, based on three 24 hour VLBA observing sessions, fills the areas on the sky above declination −45 where the calibrator density is less than one source within a 4 radius disk at any given di...
متن کاملThe Fifth Vlba Calibrator Survey: Vcs5
This paper presents the fifth part of the Very Long Baseline Array (VLBA) Calibrator Survey (VCS), containing 569 sources not observed previously with very long baseline interferometry in geodetic or absolute astrometry programs. This campaign has two goals: (i) to observe additional sources which, together with previous survey results, form a complete sample, (ii) to find new strong sources su...
متن کاملThe Fourth Vlba Calibrator Survey — Vcs4
This paper presents the fourth extension to the Very Long Baseline Array (VLBA) Calibrator Survey, containing 258 new sources not previously observed with very long baseline interferometry (VLBI). This survey, based on three 24 hour VLBA observing sessions, fills remaining areas on the sky above declination −40 • where the calibrator density is less than one source within a 4 • radius disk at a...
متن کاملVLBA Calibrator Survey: Astrometric and Image Results
Positions and maps of 1608 new compact sources were obtained in twelve sessions observed during 1994–2002 at the VLBA network at 8.4/2.3 GHz. These sources are recommended for use as calibrators for phase reference imaging and as geodetic sources for astrometric/geodetic VLBI applications.
متن کاملThe VLBA Imaging and Polarimetry Survey at 5 GHz
We present the first results of the VLBA Imaging and Polarimetry Survey (VIPS), a 5 GHz VLBI survey of 1,127 sources with flat radio spectra. Through automated data reduction and imaging routines, we have produced publicly available I, Q, and U images and have detected polarized flux density from 37% of the sources. We have also developed an algorithm to use each source’s I image to automatical...
