This HEASARC database table contains information on the so-called "Related Objects" only, as taken from the Catalog of Cataclysmic Binaries, Low-Mass X-ray Binaries, and Related Objects (7th Edition, Release 7.21, March 2014) of Ritter & Kolb. The complete catalog lists coordinates, apparent magnitudes, orbital parameters, stellar parameters of the components, and other characteristic properties of 1166 cataclysmic binaries, 105 low-mass X-ray binaries, and 500 related objects with known or suspected orbital periods. The HEASARC has for simplicity split this catalog into three Browse database tables, one for each class of objects: the present table (RITTERRBIN) containing the related binaries' data, a second one (<a href="/W3Browse/star-catalog/rittercv.html">RITTERCV</a>) containing cataclysmic binaries' data, and a third one (<a href="/W3Browse/star-catalog/ritterlmxb.html">RITTERLMXB</a>) containing the low-mass X-ray binaries' data. The literature published before 1 January 2014 has, as far as possible, been taken into account. Related objects are detached binaries consisting of either a white dwarf or a white dwarf precursor primary and of a low-mass secondary. The secondary may also be a highly evolved star. This table was last updated by the HEASARC in April 2014 based on the pcbdata.dat file from the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/B/cb">CDS Catalog B/cb</a>.
