Embodied in the PAMoC code are elements of programs distributed by other groups. In particular:

I take this opportunity to thank these authors. My modifications of their programs have been considerable. Responsibility for any erroneous use of these programs therefore remains with the present author.

It is my pleasure to thank Mark A. Spackman for useful suggestions about the implementation of the penetration energy contribution into the ECDA code.[4Spackman, M. A.  Chem. Phys. Lett. 2006, 418, 158-162.]

I am also in debt with all my colleagues at the Institute of Molecular Science and Technologies (ISTM), Milano, Italy In 2019 the Institute of Molecular Science and Technologies (ISTM), the Institute for Macromolecular Studies (ISMAC) and the Institute of Chemistry of Molecular Recognition (ICRM), operating in the Department of Chemical Science and Materials Technologies (DSCTM) of the Italian National Research Council (CNR), have merged into a single new institute, i.e. the Institute of Chemical Sciences and Technologies (SCITEC) "Giulio Natta". for their constant support of and interest in the development of the PAMoC program.

Contributors to the design of the PAMoC website

In February 2019 a Google search led me to the website www.randomservices.org created by Kyle Siegrist.[L1Kyle Siegrist, "Expository Mathematics in the Digital Age - Title Page"
Convergence (May 2006).
, L2Kyle Siegrist, "Probability, Mathematical Statistics, and Stochastic Processes"
University of Alabama in Huntsville, 31 August 2021.
, L3Kyle Siegrist on ResearchGate, L4Kyle Siegrist's profile on Random Services] The clear and appealing structure of this site, the ease of navigation, and the use of advanced (but open and standard) technologies (including small, interactive, HTML5-based web applications designed to illustrate concepts in probability, mathematical statistics, and stochastic processes) caught my attention and led me to reorganize the PAMoC site in a similar way, using the Random site as a model. The reproduction of some informative content and the use of some objects downloaded from this site (www.randomservices.org/random/) is firmly and gratefully acknowledged.

The material in this project is provided as a service to the research and educational community. No warranties are expressed or implied as to the correctness or usefulness of the material.

A very large number of tests of the PAMoC code have been performed in order to check as many options as possible, but not all the possible combinations of options have been checked. I have no doubts that errors remain. The author would greatly appreciate comments, suggestions and criticisms by the users of PAMoC; in case of errors the user is kindly requested to contact the author by E-mail, sending a copy of both input and output, or to use the Feedback facility.
