Infrared properties of cataclysmic variables in the 2 micron All-Sky Survey Second Incremental Data Release. Hoard D.W., Wachter S., Clark L.L., Bowers T.P. <Astrophys. J. 565, 511 (2002)> =2002ApJ...565..511H
ADC_Keywords: Stars, variable ; Novae ; Binaries, cataclysmic ; Photometry, infrared Keywords: accretion, accretion disks - infrared: stars - novae, cataclysmic variables - stars: dwarf novae - stars: fundamental parameters - surveys Abstract: Cataclysmic variables (CVs) have "traditionally" been observed primarily at short wavelengths because accretion-generated luminosity, which peaks in the optical-ultraviolet, dominates the radiated energy of most systems. Hence, relatively little is known about their infrared (IR) properties. Investigating CVs in the IR will contribute to the understanding of key system components that are expected to radiate at these wavelengths, such as the cool outer disk, accretion stream, and secondary star. We have compiled the near-IR J, H, and Ks band photometry of all cataclysmic variables contained in the sky coverage of the Second Incremental Data Release of the 2 Micron All Sky Survey (2MASS). This data comprises 251 cataclysmic variables with reliably identified near-IR counterparts and S/N>10 photometry in one or more of the three near-IR bands. In addition to tables containing the 2MASS data, we present a set of near-IR finding charts for selected systems. File Summary:

Note (1): The astrometric accuracy of the 2MASS PSC is better than 0.2" Note (2): We have defined each of these sub-type categories to include the following classification codes given in Downes et al. (2001, Cat. V/110): dwarf novae = ug, ugz, ugss, ugsu, ugwz novalikes = nl, ux, vy classical novae = n, na, nb, nc recurrent novae = nr, nra, nrb magnetic CVs = am, dq The uncertain/unclassified systems include the general classification code of "cv" as well as any targets with uncertain classification (denoted with ":" or "?") and/or conflicting classifications (e.g., "ug/vy"). In a few cases, to avoid "recounting" the same targets, we chose between multiple (but compatible) classifications. Note (3): Orbital periods inferred from the superhump period relation of Stolz & Schoembs (1984A&A...132..187S) are listed here, but periods described by Downes et al. (2001, Cat. V/110) as "uncertain/unreliable" are not listed. Note (4): An asterisk indicates that additional information about the CV is given in notes.dat file. The data quality flags are: rd: read flag, describing the photometry method, bl: blend flag, describing the number of profiles fit during the photometry cc: contamination flag, describing various photometry problems. Each flag is followed by a three digit code giving the flag values for the Jmag, Hmag, and Kmag columns, respectively. Acceptable values for rd are: 0: source not detected, 95% confidence upper limit magnitude is given 1: aperture photometry magnitude 2: profile-fitting magnitude all other values indicate unusable data. Acceptable values for bl are 0: source not detected, corresponding to rd=0) 1: single profile fit to isolated source values >1 indicate multiple sources detected in a small region. Acceptable values for cc are 0: not contaminated or not detected all other values indicate contaminated data (e.g., P, D, and S indicate different contamination artifacts caused by a nearby bright star, C indicates confusion with a nearby source, B indicates confusion during merging of the J, H, and Ks band data sets).

Note (1): Notes: * = Additional information about the CV is given in notes.dat file Uncertain ID = A CV for which there is insufficient or imprecise information pertaining to its optical position and/or identification that precludes identification of the near-IR counterpart. Cluster = A CV located in a star cluster that is too crowded to obtain 2MASS photometry. The cluster's NGC catalog number is given. Artifact = A CV located in the exclusion region defined around diffraction spikes of nearby bright stars. Crowded = The near-IR field around the CV is more crowded than the optical field, and conclusive identification of the CV's near-IR counterpart is not possible. Blended = The near-IR counterpart of the CV is blended with one or more additional near-IR sources in the 2MASS images.
