H/r for discs with various and metallicity. The metallicity is 0.1% in the top panel, 1.0% in the second from top panel, 2.0% in the third from top panel, and 3.0% in the bottom panel. An increasing metallicity reduces the cooling rate of the disc, making the disc hotter, and therefore increases H/r. The black lines in the plots indicate the fit presented in Appendix A.
