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.
