Ursae Majoris-type eclipsing variables.
These are eclipsers with periods usually shorter than 1 day,
consisting of ellipsoidal components almost in contact and having
light curves for which it is impossible to specify the exact times
of onset and end of eclipses. The depths of the primary and
secondary minima are almost equal or differ insignificantly. Light
amplitudes are usually <0.8 mag. in V.
The components generally belong to spectral types F-G and later.
