Note on Class: See GCVS (cat. II/139), principal classes are:
     A = Algol type      E = Eclipsing binary
     B = beta Lyr type   W = W UMa type
Note on Kopal: this class depends on Roche-lobe radii, as:
     C = Contact system  (ex. W UMa)
     D = Detached system (ex. beta Lyr)
     S = Semi-detached system (ex. Algol = beta Per)
Note on Sp:
    The colon denotes uncertain information, round brackets denote that
    the adopted spectrum for a fainter component was taken from Koch et
    al. (1970), and square brackets that the adopted spectrum was taken
    from Svechnikov (1969)


History:
  * The catalogue was keystroked at CDS in 1987 from the published table,
    which is of poor quality
  * 21-Jun-1996 (version A): following remarks by Eric Lefevre
    , a consistency check of the masses was performed
    and led to corrections to the following 14 stars:
    LR ARA   RX ARI     ZZ AUR    AK AUR    UZ CMI    UW CAP    V402 CEN
    NY CEP   V388 CYG   BO HER    LX PER    AW UMA    RV VEL    TT VEL
  * 29-Jun-1999: corrected NU SGR into UPS SGR (F. Ochsenbein)
