Persei-type (Algol) eclipsing systems. Binaries with spherical
or slightly ellipsoidal components. It is possible to specify, for
their light curves, the moments of the beginning and end of the
eclipses. Between eclipses the light remains almost constant or
varies insignificantly because of reflection effects, slight
ellipsoidality of the components, or physical variations. Secondary
minima may be absent. An extremely wide range of periods is
observed, from 0.2 to ≥10000 days. Light amplitudes are also quite
different and may reach several magnitudes
