dc.description.abstractThe effects of modeling the intrinsic curvature of the spectral energy distributions of BL Lacertae objects in the soft x-ray on the V/V M evolutionary statistic were studied. It was found that the power law approximations in the soft x-ray could cause a significant bias in V/V M towards values supporting either negative or positive evolution for BL Lacs. The effects of such a bias on the Sedentary Survey, a large sample of 150 BL Lacertae objects, were found to be negligible on average though individual effects were appreciable. The luminosity function and parametric values of evolution for pure luminosity and pure density evolution were computed for the Sedentary Sample.
