The observations were performed on 3 different seasons in 1986 January, February and July, with a 6-channel photometer attached to the 1.5m telescope if the Observatorio Astronomicao Nacional at San Pedro Martir, Baja California, Mexico. A number of standard stars were observed, and a nearby comparison star was observed for each object.1993A&A...275..201Ehttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/275/201CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/70/481 : Catalogue of Northern dwarf novae (Bruch+ 1987)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/275/201https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/275/201http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/275/201https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/275/201https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/275/201http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/275/201GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/275/201/table1 (The dwarf novae)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/275/201/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/275/201/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/275/201/table1?GETtext/xml+votable180.050000true352.44466743.7511670.0055555555555555566/3601 4790 4859 6883 9238 13678 14018 14441 14454 14899 19076 19383 21476 21576 22321 23767 24061 24466 25577 29459 29787 32244 40219 40490 40578 43947https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/275/201?format=asciiOpticaldefaultJ/A+A/275/201/table1The dwarf novaec1c1 color indexmagphot.colorfloatm1m1 color indexmagphot.colorfloatrecnoRecord number assigned by the VizieR team.
