Fig. 5: Super-pressure diversity curves.
From: The stratospheric Goldilocks zone is critical for high-altitude balloon navigation
A Diversity as a function of altitude range for a super-pressure balloon. B Marginal Diversity gain, representing the derivative of the best diversity curve A with respect to range, as a function of altitude range. An exponential function is fit to the data, with an R2 = 0.9961. The point where marginal diversity has decreased by a factor of \(\frac{1}{2}\) and \(\frac{1}{e}\) is also marked on the plot.
