Abstract:
Based on a new sample of 355 quasars with significant optical
polarization and using complementary statistical methods, we confirm
that quasar polarization vectors are not randomly oriented over the
sky with a probability often in excess of 99.9%.
Description:
The table contains linear polarization measurements for 355 QSOs.
