18. It should be noted that only the product (Formula presented) has significance in this diagram. Any system with a given (Formula presented) will have the same Landau level vs tilt diagram for the ideal, noninteracting case, regardless of what the individual values of g and (Formula presented) happen to be.
19. We note that about halfway between (Formula presented) and (Formula presented), Fig. 22(a) shows all (Formula presented) greater than 2 to have a gap of (Formula presented) Therefore, all (Formula presented) for which (Formula presented) is larger than the disorder and temperature should show minima. Indeed, in Fig. 11 at (Formula presented) and (Formula presented), all (Formula presented) up to 5 show minima, and in the high density data near those angles, all (Formula presented) up to 8 show minima. As the angle is increased, the gaps of increasingly larger (Formula presented) become fixed at (Formula presented) For example, Fig. 22(a) shows that (Formula presented) should remain (Formula presented) after (Formula presented), consistent with the data of Fig. 11 and Fig. 22(b). Furthermore, in the (Formula presented) trace in Fig. 11, all of the minima are strong because at this angle, all gaps up to (Formula presented) are (Formula presented)
