[en] The quantitative local quasar model proposed by Bell and Fort has been subjected to a critical analysis. Their quasar model requires a large number for sudden increases in the intrinsic luminosity of quasars, occurring in exactly 0.165 magnitude jumps. Such a requirement has no known physical basis. The standard error in the intrinsic redshift component z/subx/ being more than 0.05, no significance can be attached to the feature in the power spectrum of z/subx/ with a 0.1 periodicity. This conclusion has been tested by performing power spectrum analyses on samples with perfect periodicity
