Multicolour photoelectric observations of the eclipsing binaries ZZ Cru, RU
Gru and DT Lup obtained in 1965 and 1968 using Walraven ULBV filters are
presented. Photometric elements of the binaries, determined by
Wilson-Devinney's code, classify ZZ Cru as a semi-detached, RU Gru as a
detached and DT Lup as an almost detached system. Application of the Horak's
limb-darkening scan technique for computation of photometric elements is given
for these binaries.
