Abstract
We study the implications of possible off-peak measurements in the 199 5 LEP run, in regard to probing physics beyond the Standard Model, To do so, we determine the accuracy with which various nonstandard coupli ngs can be expected to be measured in the three different scan scenari os recently discussed by Clarke and Wyatt. We find that each scan scen ario allows greater sensitivity to a different set of new physics coup lings. Oblique parameters are best measured with the longest scan, whi le nonstandard fermion couplings to the Z(0) tend to be better constra ined (albeit only marginally) if all of the 1995 LEP measurements are taken on the Z(0) peak.
