Optical linear polarization measurements of quasars obtained with the Very Large Telescope at Paranal Observatory

Abstract

We report 87 previously unpublished optical linear polarization measurements of 86 quasars obtained in May and October 2008, and from April to July 2015 with the Focal Reducer and low-dispersion Spectrographs FORS1 and FORS2 attached to the Very Large Telescope at the Paranal Observatory. Of the 86 quasars, 37 have $p\ge 0.6\%$, 9 have $p\ge 2\%$, and 1 has $p\ge 10\%$.
