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We report 87 previously unpublished optical linear polarization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≥0.6%, 9 have
p≥2%, and 1 has p≥10%.
Description:
This Table contains optical linear polarization measurements of 86
quasars obtained in May 2008, 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.
