[lammps-users] coul/long

Hello,

I am trying to analytically match the potential of pair style coul/long in lammps.  What is the C constant used in the potential shown in the user manual: E=CQiQj/epsilon*r ?  

For coul/long, is the potential E=(CQiQj/epsilon*r)*(erfc(alpha*r)) for the real space portion of ewald sum?
