II/116         Photoelectric Photometry in Johnson UBVRI System (Lanz 1986)

Photoelectric Photometric Catalogue in the Johnson UBVRI System Lanz T. <Astron. Astrophys. Suppl. Ser. 65, 195 (1986)> =1986A&AS...65..195L
ADC_Keywords: Photometry, UBVRI Description: The catalog is a compilation of photoelectric photometry in the Johnson UBVRI system published prior to mid-1984. The catalog contains a total of 6849 stars in the original Johnson system (Morel and Magnenat 1978), 467 stars in the system of Kunkel and Rydgren (1979), 1150 stars in the system of Moffett and Barnes III (1979), and 252 stars in the system of Neckel and Chini (1980). The catalog is in 14 files: The first 12 files list observational data, mean values, and references for each of the four standard systems. An additional two files contain the numbering scheme of Mermilliod (1978) used to identify objects, and introductory information.
