cds-question@unistra.frvariable-starscataclysmic-variable-starsnovaeinfrared-photometrySpatial distribution, galactic model parameters and luminosity function of cataclysmic variables (CVs) in the solar neighbourhood have been found using distances estimated from the period-luminosity-colours (PLCs) relation of CVs. It can be concluded that exponential function fits better to the observational z-distributions of the whole CVs in the sample, non-magnetic CVs and dwarf novae, while the sech^2^ function is more appropriate for nova-like stars and polars. The vertical scaleheight of CVs is 158+/-14pc for the 2MASS J band limiting apparent magnitude of 15.8. The discrepancies between the theoretical and observational population studies of CVs can be at least partly removed if the sech^2^ density function is used in deriving the galactic model parameters. We estimated the vertical scaleheights of 128+/-20pc and 160+/-5pc for dwarf novae and nova-like stars, respectively. The local space density of CVs is found ~3x10^-5^pc^-3^ which is in agreement with the lower limit of the theoretical predictions. The luminosity function of CVs shows a trend toward higher space density at low luminosity, implying an increase in the number of short-period systems.2008NewA...13..133Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/NewA/13.133CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/123 : Catalog of Cataclysmic Variables (Downes+ 2001-2006)J/ApJ/565/511 : Cataclysmic variables in the 2MASS 2IDR (Hoard+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/NewA/13.133https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/NewA/13.133http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/NewA/13.133https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/NewA/13.133https://vizier.iucaa.in/viz-bin/votable?-source=J/other/NewA/13.133http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/NewA/13.133GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/NewA/13.133/table1 (Main catalogue data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/NewA/13.133/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/NewA/13.133/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/NewA/13.133/table1?GETtext/xml+votable180.050000true188.727537.62891670.0055555555555555566/158 557 763 901 928 1002 1007 1346 1387 1411 1535 1703 1781 1848 2012 2134 2154 2244 2248 2286 2309 2372 2409 2440 2661 2753 2883 2922 2964 2994 3011 3029 3041 3247 3292 3421 3541 3588 3601 3874 3908 3923 4040 4052 4173 4195 4196 4221 4279 4296 4298 4348 4356 4367 4377 4515 4723 4740 4790 4828 4844 4859 4860 4990 4999 5210 5307 5369 5485 5558 5570 5650 5675 5802 5833 5883 5918 5947 6052 6075 6076 6237 6242 6274 6319 6456 6467 6528 6598 6694 6883 7046 7168 7199 7210 7233 7306 7320 7371 7577 7582 7636 7733 7752 7828 7873 7906 7917 7980 8269 8474 8552 8559 8596 8693 9238 9267 9333 9425 9467 9484 9577 9578 9747 10232 10799 11084 11112 11351 11485 12053 12114 12288 12479 12496 12554 12568 12625 12830 12850 12859 12888 12896 12932 12933 12976 12979 12983 12996 13024 13099 13106 13216 13421 13458 13678 13681 13682 13849 13971 13975 14000 14018 14060 14109 14184 14201 14254 14393 14431 14441 14452 14477 14574 14630 14701 14722 14801 14899 14906 14964 15014 15036 15041 15090 15105 15165 15177 15255 15340 15368 15385 15386 15430 15502 15689 15949 16041 16046 16072 16078 16280 16394 16529 16550 16608 17248 17600 17722 17818 17886 18207 18229 18590 18703 18817 18844 18859 19009 19039 19363 19383 19574 19592 19639 19950 20066 20106 20168 20618 20773 20940 21476 21553 21567 21576 21630 21705 22020 22076 22129 22166 22321 22464 22485 22573 22716 22813 22828 22890 22977 23432 23623 23767 23953 24061 24118 24297 24405 24417 24466 24487 24506 24897 25232 25481 25577 25709 25952 26157 26446 26645 26780 26835 26979 26995 27004 27204 27223 27343 27386 27545 27612 27620 27945 27982 28104 28396 28561 28697 28702 28705 28720 28787 28870 28879 28960 29217 29221 29307 29406 29459 29787 29795 29844 29900 30001 30029 30044 30284 30306 30315 30469 30502 30521 30543 30577 30647 30652 30682 30717 30949 30993 31309 31331 31357 31416 31684 31774 31789 31866 31997 32006 32017 32244 32248 32472 32552 32765 32845 32862 33067 33088 33096 33360 33378 33403 33448 33498 33713 33822 33856 33866 34066 34097 34139 34297 35333 35824 36008 36020 36129 36130 36180 37000 37022 37216 37252 37888 37891 37922 37968 38045 38348 38421 38492 38745 38747 38919 39006 39192 39207 39253 39397 39459 39720 39775 39991 40037 40165 40235 40271 40460 40490 40520 40578 40640 41214 41543 41583 41647 41653 41738 41822 42042 42143 42267 42289 42324 42387 42520 42547 42653 42837 42910 43087 43321 43386 43606 43660 43722 43882 43908 43940 43947 44245 44518 44561 45098 45254 45580 45635 45671 45805 45814 45855 45927 46002 46130 46500 46591 46737 46739 46964 46969 47161 47313 47496 47525 47540 47851 47864 48034 48098 49004 49112 491231.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/NewA/13.133?format=asciiInfrareddefaultJ/other/NewA/13.133/table1Main catalogue datarecnoRecord number assigned by the VizieR team.
