The properties of cataclysmic variables in photometric Hα surveys
We report on the properties of 71 known cataclysmic variables (CVs) in photometric Hα emission-line surveys. Our study is motivated by the fact that the Isaac Newton Telescope (INT) Photometric Hα Survey of the northern galactic plane (IPHAS) will soon provide r′, i′ and narrow-band Hα measurements down to r′≃ …
