cds-question@unistra.freclipsing-binary-starsphotometryA photometric analysis of the W UMa systems V 700 Cyg and AW Vir, based on photoelectric B and V light curves, is presented. Since no spectroscopic mass-ratio is available, the q-search method was applied to find the preliminary range of the mass-ratio in order to search for the final solution. First, an unspotted solution was carried out by using the unperturbed parts of the light curves and applying the DC program of the WD code. The final spotted solution was made by adopting spot models for the two systems. In the case of V 700 Cyg, two cool spots were placed on the primary (more massive, larger and cooler) component to explain the O'Connell effect (MaxII fainter than MaxI) and a small deficit of light just before MaxI. In the case of AW Vir, one cool spot was placed on the primary component to explain the relatively large O'Connell effect. Both objects are W-type systems with partial eclipses; V 700 Cyg is fairly evolved while AW Vir is rather unevolved.1997A&AS..124..291Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/124/291CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/124/291https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/124/291http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/124/291https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/124/291https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/124/291http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/124/291GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/124/291/table1Times of minima of V700 CygrecnoRecord number assigned by the VizieR team.
