Abstract
The photometric perturbationsB (l) h arising from both tidal and rotational distortion of a close eclipsing binary have been given in two previous papers (Livaniou, 1977; Rovithis-Livaniou, 1977). The aim of the present paper will be to find the eclipse perturbationsB 2m =B 2m, tid +B 2m, rot of a close binary exhibiting partial eclipses. This will be done giving the suitable combinations of theB (l) h 's and will make easier the application to real stars.
After a very brief introduction, Section 2 gives both theB 2m, tid andB 2m, rot for uniformly bright discs; while in Sections 3 and 4 they are given for linear and quadratic limb-darkening, respectively.
Finally, Section 5 gives a brief discussion of the results.
