Hey guys,
I have a potentially (no pun intended...ok maybe a little) stupid question. People often use log potentials to model galaxies with flat rotation curves and things and I'm currently using it to model a galactic potential for some simulation work. However none of the sources i have looked at show how one can extract the effective mass of a log potential, ie for a given log potential what is M or vice versa. I need to know the mass so i can ensure its conservation when i redistribute it and run simulations in potentials of different 'lumpiness'.
Cheers
