Description:
This Table contains linear polarization measurements (mainly in the
V band) of 203 QSOs. First time measurements have been obtained for
184 objects. Among them 109 known radio emitters, 42 BAL and
1 gravitationally lensed QSO.

Note (1): Type of object:
R = Known radio-emitter
B = Known Broad Absorption Line (BAL) QSO
RB = both R and B
U: Unknown
Note (2): Remarks are coded as follows:
N1 = polarization measurements most probably contaminated by
interstellar polarization
N2 = polarization measurements possibly contaminated by interstellar
polarization
R = observation done with the R band filter
i = observation done with the i band filter
