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

Photoelectric Photometric Catalogue in the Johnson UBVRI System

================================================================================
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.
