In the high-energy domain systematic uncertainties become a substantial fraction of attainable energy resolution of a proportional tube electromagnetic calorimeter. Sources of nonuniformity and fluctuation of calorimeter response are discussed and test data on the magnitude of the effects are presented. Possible ways of maintaining these effects under control are discussed and test data are discussed which demonstrated that such effects could in fact be monitored and corrected to less than 1%.
