We report radio detections of 18 stars. Thirteen are new radio sources, increasing the number of MCVs that are radio sources by more than twofold, from 8 to 21. Most detections are at 8.7 GHz (X-band) with a lesser number at 5.4 and 21.1 GHz (C- and K-bands). With the exception of AE Aqr, whose flux density is typically >5 mJy, the flux densities are in the range of 24-780 {mu}Jy. Thirteen of the detections show highly circularly polarized emission, which is characteristic of electron-cyclotron maser emission. The data suggest that MCVs could possibly be divided into two classes of radio emitters: those dominated by weakly polarized gyrosynchrotron emission and those by highly polarized electron-cyclotron maser emission.2017AJ....154..252Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/252CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/123 : Catalog of Cataclysmic Variables (Downes+ 2001-2006)V/113 : Cataclysmic Binaries, LMXBs, and related objects (Ritter+, 2003)B/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)I/322 : UCAC4 Catalogue (Zacharias+, 2012)J/AJ/153/144 : Spectroscopy of mCVs and other variable objectshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/252https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/252http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/252https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/252https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/252http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/252GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/252/table2 (Target list and their properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/252/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/252/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/252/table2?GETtext/xml+votable180.050000true7.203559.28952780.005555555555555556Cone search capability for table J/AJ/154/252/table34 (Radio fluxes, positions (table 3) and fractional circular polarization (table 4) of detected MCVs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/252/table34?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/252/table34?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/252/table34?GETtext/xml+votable180.050000true22.21930417-23.662480560.0055555555555555566/557 597 763 1387 1535 1694 2012 2134 2623 3041 3541 3971 4144 4173 4196 4221 4298 4367 4377 4740 4761 4905 5369 5558 5570 5864 6036 6274 6467 6528 6621 6637 6694 6838 7320 7498 7636 7733 7810 7828 7917 8552 8693 9267 9419 9484 9577 9618 9765 11112 12568 12859 13024 14000 14379 14452 15036 15090 15255 15385 15430 16072 16394 17818 18590 18703 18817 18862 19363 20618 20678 21630 21705 22020 22464 22485 22573 22830 22977 23432 24111 24297 25909 26835 27343 27545 28221 28396 28561 28830 29534 29795 29871 30029 30044 30284 30315 30993 31357 31774 31804 31997 32765 34297 35824 35988 36088 36129 36130 36181 36234 39397 39720 40235 40271 40293 40520 40640 47470 491123.578077631157449e-24 1.3981007046114396e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/252?format=asciiRadiodefaultJ/AJ/154/252/table2Target list and their propertiesSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
