Densification of the VLBA Calibrator Survey (VCS9)


Densification of the VLBA Calibrator Survey (VCS9) project has several goals: population analysis, community service, and extension of the legacy list of compact radio sources. Proposed observations will allow to homogenize the sample of compact extragalactic radio sources with correlated flux densities at baseline projection lengths greater than 3000 km. This project is aimed at increasing the area of the sky that have at least one suitable calibrator in a disk of 1.5° radius. Another obnjective is to reach completeness at 3/4 of the celestial sphere at 150 mJy level.

Goals of the project:

  1. To improve astrometric accuracy of Pan-STARRS and future LSST catalogs by
