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).
