Light-pair corrections to small-angle Bhabha scattering have been computed
in a realistic set-up for luminosity measurements at LEP. The effect of aco
llinearity and acoplanarity rejection criteria has been carefully analysed
for typical calorimetric event selections. The magnitude of the correction,
depending on the details of the considered set-up, is comparable with the
present experimental error. (C) 1999 Published by Elsevier Science B.V. All
