Abstract:
In order to determine the spatial distribution, Galactic model
parameters and luminosity function of cataclysmic variables (CVs), a
J-band magnitude limited sample of 263 CVs has been established using
a newly constructed period-luminosity-colours (PLCs) relation which
includes J,KsJ,Ks and W1W1-band magnitudes in 2MASS and WISE
photometries, and the orbital periods of the systems. This CV sample
is assumed to be homogeneous regarding to distances as the new PLCs
relation is calibrated with new or re-measured trigonometric
parallaxes.
Description:
The data sample used in construction of the new PLCs relation consists
of CVs in Table 1 including their classes, orbital periods (Porb),
trigonometric parallaxes (π) relative parallax errors
(σ_π/π), 2MASS J and Ks magnitudes and WISE W1 magnitudes.
