Hi
normally the effective mass variable are normalised such that the sum of the square of each participative mass value, per direction adds up to the total mass of the object, so what I often do is to normalise mode_mass_x^2 / Total_Mass and check that I select sufficient modes to get 70-80% or more of the total mass per direction

Good luck
