Maximum informational entropy method (MEM) is a known way to describe extensively complicated decay distributions. Superiority of this method was shown on complicated cases, e.g. for description of changes of tryptophan environment heterogeneity during protein conformational changes and even as a viable tool for fluorescent response-based qualitative analysis of cell cultures. Unlike for other approaches, in MEM there is no preliminary assumption on a distribution kind and thus the method produces completely uncorrelated results without "dangling" small intensity components in case two or more distributions are supposed to join. The MEM, despite its outstanding possibilities is not widespread enough, not found in most time-correlated single photon counting (TCSPC) processing software and, to the best of our knowledge, was never implemented in an opensource format, either available as a proprietary software script or in a form of purely mathematical derivations.
