Abstract:
We create and analyse the largest up-to-date all-sky compilation of
the interstellar optical polarization data supplemented by the
reddening data This compilation includes 13 data sources with optical
interstellar linear polarization for 3871 Gaia DR2 and Hipparcos stars
within 500pc, which do not exhibit a considerable intrinsic
polarization. These data are analysed together with five 3D maps and
models of the reddening E(B-V). We consider variations of the
polarization degree P, position angle theta, and polarization
efficiency P/E(B-V) with Galactic coordinates, distance R, and
dereddened colour. P shows a maximum at the Gould Belt mid-plane. P/R
drops in the Local Bubble by several times defining a boundary of the
Bubble at P=0.1 per cent. All the data sources of the reddening,
except Lallement et al., show a drop of P/E(B-V) in the Bubble. The
spatial- and colour-dependent variations of P and E(B-V) outside the
Bubble compensate each other, resulting in a nearly constant P/E(B-V).
A giant envelope of aligned dust dominates at middle and high
latitudes outside the Bubble. The Markkanen's cloud, the North Polar
Spur, and some other filaments are parts of this envelope.
Description:
The tables 1, 2, 3, 6 are described in the source paper. The master
table table1.dat contains the polarization and reddening data for 5910
stars, i.e. not only for 3871 stars used in the study but also for
some stars with lower precision of the polarization data. The
table1.dat can be used in further investigations. All the E(B-V)
estimates are interpolated from the 3D reddening maps and models by
use of the distances from Bailer-Jones+, 2018 (2018AJ....156...58B 2018AJ....156...58B,
Cat. I/347).
