Proportion of odd components in H(φ). Oddness factor F_odd in the plane of skewness (A′ that ranges from 0 to its maximum allowed value of 1 − W′) and type parameter (B′ shown here between −1 and 1) at four different values of spike width. The interaction function is rarely totally even or totally odd. Even predominantly evenness (F_odd < 0.1) or predominantly oddness (F_odd > 0.9) occurs in tiny pockets of the parameter space. For most of the type parameter and skewness values H(φ) is a mixture of both even and odd modes.
