Binaries, eclipsing An iterative method has been used to compute the geometric and physical parameters of 1048 eclipsing binary stars.

W UMa) D = Detached system (ex. beta Lyr) S = Semi-detached system (ex. Algol = beta Per) --- Sp Spectrum The colon denotes uncertain information, round brackets denote that the adopted spectrum for a fainter component was taken from Koch et al.
