ADC_Keywords: Clusters, open ; Photometry, Vilnius ; Photometry, CCD Keywords: stars, fundamental parameters - clusters: individual: M 67 - methods: observational, data analysis, photometric - Vilnius photometric system Abstract: Seven color CCD photometry in the Vilnius system, supplemented by the Cousins I passband, has been obtained for 412 stars down to V=16mag in the M67 open cluster area. A special method of flat-fielding, giving high accuracy photometry, was used. Photometric spectral types and interstellar reddenings of all stars were determined. The mean mean reddening of the cluster stars is E(B-V)=0.04mag and the distance is 770pc. File Summary:
