 * <code>root</code> - root particle for EvtGen. <code>vpho</code> (virtual photon) should be used for non-resonant processes
 ** Acceptable root particles: <code>vpho</code>, <code>J/psi</code>, <code>psi(2S)</code>, <code>psi(3770)</code>, <code>psi(4040)</code>, <code>psi(4160)</code>, <code>psi(4415)</code>. For more details see Generation/GenTools/GenWrappers/python/EvtGenTools.py in Aurora.
-* <code>ecms</code> - Total center-of-mass energy. This parameter should be set for virtual photon. This parameter is ignored for if root particle is a resonance (it's mass is the center-of-mass energy)
+* <code>ecms</code> - center-of-mass energy (mass of the root particle). The parameter <code>ecms</code> must be set for virtual photon while for other root particles (<math>J/\psi</math>, <math>\psi(2S)</math>, ...) this parameter is optional. Mean mass of the root particle is adopted if <code>ecms</code> is omitted.
 * <code>nevt</code> - number if events to be gnerated
 * <code>ip</code> - uniform 3D smearing (in mm) for the primary vertex
