Enlisted contact binaries are divided into five groups according to the type and quality of the available observations and parameters. For all systems the ephemeris for the primary minimum, minimum and maximum visual brightness and equatorial coordinates are given. If available, photometric elements, (M_1_+M_2_)*(sin)i^3^, spectral type, parallax and magnitude of the O'Connell effect are also given. Photometric data for several systems are augmented by new observations. The quality of the available data is assessed and systems requiring modern light-curve solutions are selected. Selected statistical properties of the collected data are discussed.</description><source format="bibcode">2003CoSka..33...38P</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/V/119</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=V/119</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=V/119</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=V/119</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=V/119</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=V/119</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=V/119</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table V/119/catalog (*Catalogue of the field binary stars)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/V/119/catalog?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/V/119/catalog?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/V/119/catalog?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>347.883694</ra><dec>36.893086</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/147 454 474 497 739 1118 1164 1291 1314 1679 1684 1708 1919 1933 2320 2436 2452 2488 2499 2702 2865 2907 2939 2941 2952 2988 3002 3042 3156 3201 3444 3559 3703 3707 3722 3874 3912 3955 4020 4078 4146 4254 4298 4425 4427 4698 4719 5110 5212 5414 5427 5503 5602 5656 5836 6312 6375 6861 7262 7606 8040 8064 8357 8579 8656 8716 8871 8992 9008 9107 9167 9256 9415 9498 9514 9529 9576 9578 9583 9585 9608 9629 9667 9780 9890 9951 10002 10030 10183 10261 10326 10336 10601 10648 10775 10794 10809 10923 11100 11162 11181 11278 11290 11337 11352 11395 11486 11650 12792 12833 12849 12851 12885 12995 13123 13126 13159 13181 13618 13699 13772 13777 13818 13859 13908 14007 14056 14198 14217 14219 14227 14245 14263 14337 14398 14441 14481 14528 14537 14562 14619 14643 14666 14698 14723 14873 14891 14908 14916 14947 14959 15130 15132 15171 15179 15204 15551 15662 15795 15835 16058 16186 16719 16820 17310 17328 18016 18129 18234 18302 18362 18902 19027 19075 19448 19623 19698 19914 19998 20270 20993 21448 21919 21925 21950 21969 22071 22080 22081 22117 22122 22138 22139 22241 22249 22444 22548 22579 22662 22680 22696 22786 22872 22902 22929 23357 23751 24232 24370 24377 24378 24391 24616 24628 24983 25374 26097 26151 26231 26380 26390 26391 27017 27116 27250 27481 27603 27639 27770 27852 27984 28008 28084 28105 28129 28143 28149 28296 28432 28450 28485 28582 28679 28809 28830 28849 29027 29512 29795 29810 29880 30129 30220 30237 30400 30491 30536 30540 30564 30565 31148 31604 31778 31781 31785 31843 31886 31944 31950 32110 32240 32245 32307 32477 32500 32587 32691 32713 32722 32787 32828 32838 32910 32999 33102 33323 33372 33517 33837 34371 34454 35025 35115 35208 35378 35422 35512 35741 36484 36494 36517 36650 36805 36915 37024 37725 37789 37890 37910 38009 38310 39035 39220 39245 39933 40030 40138 40427 40682 41514 41655 41705 41726 41864 41983 42060 42355 43013 43027 43290 43355 43379 43455 43729 44514 44772 44945 44981 45215 45282 45287 45597 45826 46058 46084 46298 46320 47030 47131 47243 47289 47825 48023 49047</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/V/119?format=ascii</footprint><waveband>Optical</waveband></coverage><tableset><schema><name>default</name><table><name>V/119/notes</name><description>Individual notes</description><column><name>recno</name><description>Record number assigned by the VizieR team.
