Abstract
IN formulating the purpose of their note on the optical luminosity fluctuations of 3C 273, Manwell and Simon1 confuse the conventional terms “random”, “random process” and the concept of statistical independence. We emphasize that our statement in ref. 3 (see also refs. 4 and 5) is based on the fact that the light curve of the quasi-stellar source 3C 273 shows that a quasar nucleus is a system with a high self-interaction, and the rapid (in comparison with the quasi-period of the 3C 273 light curve) variations of optical radiation are conditioned by internal random causes.
