ABSTRACT WE have shown1 that a light curve similar to that of the quasi-stellar source 3_C_ 273 can be generated by a superposition of unit light curves occurring at random times. Gudzenko,
Ozernoy and Chertoprud2 have argued (1) that the distribution of the observed luminosities should be expected to be Gaussian on our model, and (2) that the observed distribution is not
Gaussian, so that the luminosity curve cannot be regarded as the superposition of random events. The purpose of this communication is to question the validity of both arguments and to show
that the luminosity record may still be considered to be of random origin. Access through your institution Buy or subscribe This is a preview of subscription content, access via your
