Abstract:
Polarization data are given for stars whose polarizations are mostly
interstellar which were observed for various programs with the
University of Wisconsin spectropolarimeter (HPOL) during 1989-1994,
1995-2003 and 1995-2004
Description:
HPOL takes the whole wavelength range in two steps, about
3000-6000Å and 6000-10500Å. HPOL data are processed
using a software package developed for that purpose.

Note (1): Distances for HD100340 is from Martin (2006AJ....131.3047M 2006AJ....131.3047M),
HD99835 and HD100436 are spectroscopic parallaxes assuming they
are giants, the rest are from Hipparcos parallaxes.
