Abstract:
A large sample of white dwarfs is selected by both proper motion and
colours from the Pan-STARRS 1 3π Steradian Survey Processing
Version 2 to construct the white dwarf luminosity functions of the
discs and halo in the solar neighbourhood. Four-parameter astrometric
solutions were recomputed from the epoch data. The generalized maximum
volume method is then used to calculate the density of the
populations. After removal of crowded areas near the Galactic plane
and centre, the final sky area used by this work is 7.833sr, which is
83 per cent of the 3π sky and 62 per cent of the whole sky. By
dividing the sky using Voronoi tessellation, photometric and
astrometric uncertainties are recomputed at each step of the
integration to improve the accuracy of the maximum volume.
Interstellar reddening is considered throughout the work. We find a
disc-to-halo white dwarf ratio of about 100.
Description:
This is table A1 of the article, which is the full catalogue used to
generate the Voronoi Tessellation containing 14598 sources. A number
of these sources were only used to model the survey properties but
were not directly used in computing the WDLFs. See Section 5 for the
selection criteria for the various WDLFs. The joint Catalogue ID and
Object ID forms an unique ID, however, this is not unique over
different processing versions and data releases.
