About a year ago I wrote a script to analyze the output of simulations of stellar systems, to extract information useful for understanding the physical processes that underlie the long term evolution of these systems.
It was meant as a bunch of quick and dirty functions for calculating quantities such as the average gravitational potential as a function of radius, the minimum and maximum radii associated with orbits in such a potential for every star, etc...
After a while I forgot about it but now I decided to refactor and write it properly so it can be shared with other people (especially students) who may need to plot physical quantities in a simulation either as a sanity check or to track e.g. heat transport, stellar evaporation, and other phenomena.
