Descriptive statistics for density curves in Fig 1, showing the effects of smoothing.

Both mean and median are reported as the curves sometimes do not follow a normal distribution. Probabilities < 0.05 indicate a statistically significant result that smoothing decreases the topographic metric (p < 0.05), and probabilities > 0.95 indicate a statistically significant result that smoothing increases the topographic metric (p > 0.95). The 2.5% and 97.5% quantiles are given to represent the 95% confidence interval. Triangle counts of L = low (< 210), ML = medium-low (210–1799), MH = medium-high (1800–9999), and H = high (10000+). Bold p-values are significant for greater than zero, bold and italics for less than zero.
