Cataclysmic Variables Catalog (2006 Final Edition)
This catalog contains data for a large number of objects that have been classified as cataclysmic variables (CVs) as well as a smaller number of objects that are now not considered to be cataclysmic variables, but were originally classified erroneously as such. As of 2000 December, 40% of the objects in this catalog were dwarf novae, with another 30% being novae, and the rest being mostly nova-like variables; also as of this date, a large fraction (90%) of the CVs had references to published finding charts, while 64% of the objects had published spectra. The catalog includes coordinates measured in the reference frame of the Hubble Space Telescope Guide Star Survey for non-novae and from the literature for novae. Also given are the variability type, the magnitude range, orbital periods, flags indicating the existence of relevant space-based observational datsets, references to finding charts and spectroscopy, the galactic latitude and longitude, and the year of outburst (for novae). This edition also includes plate identification information for the coordinate measurements, and a reference to the classification. The Catalog and Atlas of Cataclysmic Variables (Downes et al. in 2001, PASP, 113, 764 and <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a>) presented here is the ASCII Report mentioned in Section 2.1 of the PASP paper, and is similar to the previously published versions of the CV Catalog (e.g., Downes, Webbink and Shara 1997, PASP, 109, 345, Table 1). The online version of the CV Catalog at <a href="http://archive.stsci.edu/prepds/cvcat/">http://archive.stsci.edu/prepds/cvcat/</a> contains additional data on these systems not included in this database, including finding charts. For a complete authoritative and up-to-date description of the CV Catalog, refer to <a href="http://archive.stsci.edu/prepds/cvcat/description.html">http://archive.stsci.edu/prepds/cvcat/description.html</a>, from which the HEASARC has constructed this help file.

Outburst Catalog of Dwarf Novae-type and Other Cataclysmic Variables
This outburst catalog contains a wide variety of observational properties for 722 dwarf nova-type (DN) cataclysmic variables (CVs) and 309 CVs of other types from the Catalina Real-time Transient Survey (CRTS). In particular, it includes the apparent outburst and quiescent V-band magnitudes, duty cycles, limits on the recurrence time, upper- and lower-limits on the distance and absolute quiescent magnitudes, color information, orbital parameters, and X-ray counterparts. These properties were determined by means of a classification script presented in the reference paper. The DNs in the catalog show a correlation between the outburst duty cycle and the orbital period (and outburst recurrence time), as well as between the quiescent absolute magnitude and the orbital period (and duty cycle). This is the largest sample of dwarf nova properties collected to date (2016). Besides serving as a useful reference for individual systems and a means of selecting objects for targeted studies, it will prove valuable for statistical studies that aim to shed light on the formation and evolution of cataclysmic variables. The CRTS identifies transients in the data from the Catalina Sky Survey (Larson et al. 1998, BAAS, 30, 1037; 2003, BAAS, 35, 982), a photometric survey that searches for Potentially Hazardous Asteroids and Near Earth Objects. Three sub-surveys constitute the Catalina Sky Survey, namely the original CSS (Catalina Schmidt Survey), the MLS (Mt Lemmon Survey) based in Arizona, and the SSS (Siding Spring Survey) in Australia, which ended on 2014 July 5. The field of view and typical limiting magnitude for each survey (at ~30 s integrations) are 8.2 degrees and V~19.5 mag for the CSS, 1.1 degrees and V~21.5 mag for the MLS, and 4 degrees and V~19 mag for the SSS. Together, these surveys cover 30, 000 deg<sup>2</sup> between -70 and +70 degrees Declination (see Drake et al. 2014, MNRAS, 441, 1186 for more details). The entire zone within 15 Degrees of the Galactic Plane is avoided due to overcrowding, as are the Magellanic Clouds. The properties of the cataclysmic variables in this catalog are derived from the long-term optical light curves from the CRTS, as well as magnitudes, fluxes and orbital parameters from the SDSS, 2MASS, UKIDSS, ROSAT, Chandra, XMM and WISE catalogs, and from the Catalog of Cataclysmic Binaries, Low-Mass X-Ray Binaries and Related Objects (RKCat: Ritter and Kolb 2003, A&A, 404, 301, available at the HEASARC as the RITTERCV, RITTERLMXB and RITTERRBIN tables). This table was created by the HEASARC in October 2017 based on the <a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/456/4441">CDS catalog J/MNRAS/456/4441</a> file catalog.dat. .

Sloan Digital Sky Survey I/II Cataclysmic Variables Catalog
The reference paper completed the series of cataclysmic variables (CVs) identified from the Sloan Digital Sky Survey (SDSS) I and II. The coordinates, magnitudes, and SDSS spectra of 33 more CVs were presented. Among the 33 are eight systems known prior to SDSS (CT Ser, DO Leo, HK Leo, IR Com, V849 Her, V405 Peg, PG1230+226, and HS0943+1404), as well as nine objects recently found through various photometric surveys. Among the systems identified since the SDSS are two polar candidates, two intermediate polar candidates, and one candidate for containing a pulsating white dwarf. A complete summary table of the 285 CVs with spectra from SDSS I/II which were listed in the reference paper and the 7 previous papers in the series is contained herein. This table was created by the HEASARC in January 2012 based on an electronic version of Table 6 from the reference paper which was obtained from the AJ web site.
