Abstract:
We have measured the interstellar polarization for 2400 stars at the
distances of up to 600pc and within 60 degrees and 30 degrees from
the north and south Galactic poles. These data were used to make
interstellar polarization maps of the regions around the north (b>30)
and south (b←60) poles. The new maps give wider and higher resolution
views of interstellar polarization at high galactic latitudes and show
significant asymmetries in the polarization, one in the northern sky
directly across the local spiral and the second between the northern
and southern Galactic hemispheres.
Description:
Polarization data for 2400 stars measured with the DiPol-1 and DiPol-2
CCD polarimeters at the 60cm KVA remote-controled telescope at La
Palma (Canary Islands, Spain) are presented. For each star the star
number (either from HD or BD catalogs), galactic coordinates (l, b),
measured polarization (in percents), error of polarization,
polarization angle (in degrees), error of polarization angle, and the
parallax (in mas) are given.

Note (1): Polarization angle is given in standard equatorial coordinate
system i.e.,the angle of polarization is measured from direction to
the celestial north counter-clockwise.
Note (2): Parallax is taken from SIMBAD under condition that plx>2*error(plix).
Note (3): if the polarization was measured in the V band, the corresponding
note is given, otherwise the polarization was measured in the white
light (unfiltered).
