The theoretical accuracy of the program TOPAZ0 in the large-angle Bhabha ch
annel is estimated. The physical error associated with the full Bhabha cros
s section and its forward and backward components separately is given for s
ome event selections and several energy points of interest for LEP1 physics
, both for the s and non-s contributions to the cross section. (C) 1999 Pub
