5.4.1 A few potentials

Here we list some of the standard potentials available in NEMO, in a variety of units, so not always $G=1$!

Remember that most NEMO program use the keywords potname= for the identifying name, potpars= for a list of parameters as listed below and an optional potfile= for the few that have an associated datafile for the potential. The parameters listed in potpars= will always have as first parameter the pattern speed in cases where rotating potentials are used. A Plummer potential with mass 10 and core radius 5 would be hence be supplied as: potname=plummer potpars=0,10,5.
