cds-question@unistra.frgalaxiesphotometryredshiftedBased on photometry of the brightest blue stars we derived distance moduli for NGC 628 and its dwarf irregular companions: DDO 13, UGC 1171, UGC 1104, and K 10. The mean modulus of the group is estimated to be 29.46 mag with a formal (internal) error of 0.11. The total mass to luminosity ratio of 40M_{sun}_/L_{sun}_ seems sufficient for NGC 628 to keep its companions in bound orbits.1996A&AS..119..499Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/119/499CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/119/499https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/119/499http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/119/499https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/119/499https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/119/499http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/119/499GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+AS/119/499/table1CCD photometry of the brightest stars in NGC628recnoRecord number assigned by the VizieR team.
