Long-baseline calibrator survey

The Long-Baseline Calibrator Survey (LBCS) is aimed at identifying suitable for calibrating the highest-resolution observations made with the International LOFAR Telescope. Suitable sources must contain significant correlated flux density at frequencies around 110−190 MHz on scales of a few hundred milliarcseconds. For a description of the survey see Jackson et al. (2016).

Data products from the survey are available on this site. You may search the catalogue in a particular region of the sky or download a FITS table.
