112 A1 --- Class *[ABEW] Traditional Classification
from GCVS (Kukarkin et al, cat. II/139)
114 A1 --- Kopal *[CDS] Kopal's geometrical classification
116-130 A15 --- Sp *Spectrum
--------------------------------------------------------------------------------
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)
