Calculating total coulomb energy per particle

Dear Lammps Users,
I am using Lammps for a particular study and need to calculate the total coulombic energy per particle. I am using kspace style as pppm. I have the following questions:

  1. Does ‘ecoul’ give the short range coulombic energy per particle or the total short range coulombic energy summed over all particles?
  2. Similarly ‘elong’ gives long range coumbic energy per particle or summed over all particles?
  3. To get the total coulombic energy is it enough to add ecoul+elong outputs? I believe to get the total coulombic energy per particle I will divide (ecoul+elong) by the total number of particles.

Please clarify my doubts.
