 Returning to the full range of formula_6 rather than just primes, it is seen that other peaks associated with specified lowest factors of formula_6 can also be fitted by a Gaussian, but only on their lower shoulder.The upper shoulder, being formed by an aggregate of subsidiary peaks, lies above the simple Gaussian form.The relative heights of the peaks in the total histogram are representative of the populations of various types of formula_6 having differing factors.
