  The dependencies of the phase of eclipse of the white dwarf's centre and the
durations of the ascending and descending branches of the light curve on the
binary system's parameters were computed using the spherically-symmetric
approximation and the more accurate model of the elliptical projection onto the
celestial sphere of the companion (red dwarf) that fills its Roche lobe. The
parameters of eclipses in the classical eclipsing polar OTJ 071126+440405 = CSS
081231:071126+440405 were estimated.
