cds-question@unistra.frvariable-starsinterferometryvisible-astronomyh-alpha-photometryHigh spatial resolution observations of the H{alpha}-emitting wind structure associated with the luminous blue variable star P Cygni were obtained with the Navy Prototype Optical Interferometer. These observations represent the most comprehensive interferometric data set on P Cyg to date. We demonstrate how the apparent size of the H{alpha}-emitting region of the wind structure of P Cyg compares between the 2005, 2007, and 2008 observing seasons and how this relates to the H{alpha} line spectroscopy. Using the data sets from 2005, 2007, and 2008 observing seasons, we fit a circularly symmetric Gaussian model to the interferometric signature from the H#-emitting wind structure of P Cyg.2010AJ....139.2269Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/139/2269CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/139/2269https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/139/2269http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/139/2269https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/139/2269https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/139/2269http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/139/2269GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/139/2269/table2Calibrated H{alpha} squared visibilities of P CygrecnoRecord number assigned by the VizieR team.
