Mean column density of Cepheids within a projected distance rcosb from the Sun. The Berdnikov Cepheids are given in the solid (blue) curve, and the dashed (red) curve represents simulated data using the radial distribution model. Note the plateau of constant density between 0.5 and 1 kpc indicating that the Berdnikov catalogue is complete within 1 kpc from the Sun.
