Multiple Systems

Abstract:
   Magnitudes and colors have been measured for components in individual 
   double and multiple systems by many observers. Lists containing these 
   data are scattered across various publications. This catalog of the 
   available observations was created for the guidance of those astronomers 
   who intend to make photoelectric investigations of visual double and 
   multiple systems.

Introduction:
   The UBV magnitudes and colors have been compiled mainly from lists by:
     Alexander           (1970)
     Andrews & Thackeray (1973)
     Burnichon & Garnier (1976)
     Eggen               (1963, 1965, 1966, 1968)
     Johnson             (1953)
     Landolt             (1968, 1969, 1971)
     Lutz                (1971)
     Lutz-Lutz           (1977)
     Tolbert             (1965)

   V magnitudes and (b-y) colors, reduced to the UBV system, are from:
     Lindroos            (1981)
     Mechler             (1976)
     Mechler & McGinnis  (1978)
     Oblak               (2978)
     Oblak & Chareton    (1980)

   The data for each system appears on more than one line.

   The data file contains the name of the system (upper line HD or BD, lower 
     line NGCDS number), approximate RA and Dec (Epoch 2000), Components, 
     mean V magnitude with number of observers, mean (B-V) color with number
     of observers, mean (U-B) color with number of observers, spectral type 
     from HD if available or from observer if in parentheses, and the 
     approximate value of the distance (apparent separation = Sep, orbital 
     motions = orb) in arcsec, in most cases taken from the Index Catalogue 
     of Visual Double Stars, or from observer.
