Description:
    The semi-detached eclipsing binary system BP Muscae has been analysed
    using the Wilson-Devinney program. The physical and orbital parameters
    have been determined through a self-consistent simultaneous solution
    of light curves in seven colours and of the radial velocity curves of
    both components. The 373 photometric measurements of BP Mus in the
    7-colour GENEVA system are listed in the table. P and Q are the
    weights in colours and V magnitude (see Rufener, 1988, Cat. II/169).

Note (1): Photometric weight:
     4: observation of exceptional quality whose correlation with
        standards is remarkably well assured.
     3: normal weight for all the good measurements conveniently
        correlated with standards.
     2: weight conferred as soon as the least doubt exists as to the
        transparency or correlation with standards.
     1: weight conferred as soon as no certainty of good transparency
        and good correlation with standards can be obtained (case of
        partial night for instance).
     0: this weight sanctions all measurement for which an objective
        risk of error exists.
