cds-question@unistra.frvariable-starsinfrared-photometryvisible-astronomyphotometrytrigonometric-parallaxUsing a filter in the GROWTH Marshal based on color and the amplitude and timescale of variability, we have identified 372 objects as known or candidate cataclysmic variables (CVs) during the second year of the operation of the Zwicky Transient Facility. From the available difference imaging data, we found that 93 are previously confirmed CVs and 279 are strong candidates. Spectra of four of the candidates confirm them as CVs by the presence of Balmer emission lines, while one of the four has prominent HeII lines indicative of containing a magnetic white dwarf. Gaia EDR3 parallaxes are available for 154 of these systems, resulting in distances from 108-2096pc and absolute magnitudes in the range of 7.5-15.0, with the largest number of candidates between 10.5 and 12.5. The total numbers are 21% higher than from the previous year of the survey with a greater number of distances available but a smaller percentage of systems close to the Galactic plane. Comparison of these findings with a machine-learning method of searching all the light curves reveals large differences in each data set related to the parameters involved in the search process.2021AJ....162...94Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/162/94CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/696/870 : Catalina Real-time Transient Survey (CRTS) (Drake+, 2009)J/ApJ/788/48 : X-ray through NIR photometry of NGC 2617 (Shappee+, 2014)J/MNRAS/441/1186 : Cataclysmic variables from CRTS (Drake+, 2014)J/AJ/159/198 : Cataclysmic variables in ZTF 1st-yr (2018-2019) (Szkody+, 2020)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/162/94https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/162/94http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/162/94https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/162/94https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/162/94http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/162/94GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/162/94/table1 (Known confirmed catclysmic variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/94/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/94/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/94/table1?GETtext/xml+votable180.050000true0.37691675.10652780.005555555555555556Cone search capability for table J/AJ/162/94/table2 (Catclysmic variables candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/162/94/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/162/94/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/162/94/table2?GETtext/xml+votable180.050000true0.593291742.70366670.0055555555555555566/67 70 179 475 604 732 935 953 994 1002 1010 1138 1175 1319 1360 1433 1472 1500 1545 1639 1703 1858 2079 2172 2229 2235 2244 2248 2280 2286-2287 2309 2329 2365 2372 2377 2385 2474 2507 2509 2548 2552 2567 2577 2723 2731 2765 2769 2876 2891 2940 2947 2964 2969 3013 3079 3258 3447 3509 3741-3742 3839 3923 3991 4149 4367 4626 4740 4782 4844 5405 5569 5727 5833 5864 5929 6068 6154 6227 6257 6299 6315 6385 6566 6570 6588 6599 6611 6671 6684 6718-6719 6803 6888 6921 6939 6970 7040 7097 7105 7114 7194 7199 7240 7320 7430 7514 7611 7659 7916 7924 8017 9189 9231 9536 9701 9756 10945 11230 11332 11461 11496 11766 12039 12133 12419 12479 12502 12525 12615 12646 12723 12744 12748 12769 12830 12847 12854 12861 12872 12876 12883 12895 12902 12918 12941 12975 12992 13007 13009 13019 13062 13069 13088 13096-13097 13128 13156 13185-13186 13281 13330 13458 13479 13511 13565 13595 13659 13680 13721 13743 13775 13785 13803 13807 13827 13829 13832 13846 13852 13907 13914 13937 13959 13969 13989 14038 14052 14059 14094 14147 14213 14229 14263 14375 14413 14415 14477 14510 14536 14586 14655 14657 14720 14757 14781-14782 14792 14833 14837 14876 14934 14951 14954 14972 14986 15030 15058 15088 15155 15163 15216 15234 15271 15315 15373 15408 15523 15530 15721 15816 15842 15869 15876 15879 15895 15907 15979 16009 16036 16066 16276 17469 17767 18329 18975 19002 19474 19504 19526 19822 19828 19937 20066 20128 20214 20318 20384 20927 21410 21581 21858 22166 22170 22216 22382 22520 22894 22988 23050 23100 23127 23303 23605 23743 23871 23880 23953 23995 24032 24054 24126 24131 24190 24313 24390 24415 24481 25818 25888 26171 26524 26588 26748 27291 27377 27640 27913 27955 28118 28127 28194 29115 29329 29347 29359 29459 29496 29625 29831 29844 29895 29938 29949 29962 30134 30142 30306 30526 30578 30612 30668 30682 30684 30710 31000 31019 31166 31176 31464 31502 31612 31689 31699 31745 31755 31766 31840 31852 31881 31923 31958 31966 32005-32006 32153 32155 32159 32209 32244 32294 32341 32354 32375 32378 32615 32655 36670 40255 40341 44513 48546 48724 48745 48780https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/162/94?format=asciiOpticalInfrareddefaultJ/AJ/162/94/table1Known confirmed catclysmic variablesZTFZTF identifiermeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
