Abstract:
The results of a BVR photometry observations are presented for
multiple stars visual subsystems (table2.dat). The objects
(table1.dat) were observed in 1996 with the 60 cm and 1 m telescopes
at Maidanak Observatory (Uzbekistan) by aperture and scanning
photometers. The positional parameters and physical relation of visual
subsystems are also given (table4.dat).
