Analytical calculations have been used to describe the calorimeter event selection in small-angle electron-positron scattering at LEP1. The first-order QED correction to the Born cross section has been derived with leading log and next-to-leading log approximations. The second- and third-order corrections are computed with leading accuracy. Our analytical results are given and compared with the corresponding results obtained with the use of the Monte Carlo generator BHLUMI.
