The experimental sequence of the values of the modulation factor in a modulated Bayard-Alpert gauge for He, Ne, At, and Kr is explained on ground of the differences in shape of the corresponding ionization cross-section curves. A short discussion concerning the dependence of the modulation factor on electron current and filament-grid spacing is also given.
