a The differences in the deposit thinning based on changes in disk radius. M, H, and K values are the same used in Fig. 3, only radius, R, changes between curves. The χ2—criterion for the goodness of fit for R = 10 km is 1800, whereas for R = 5 km χ2 is 2200. b The thinning of the deposit using different diffusion coefficients K; M, H, and R values are the same as in Fig. 3. c Change in the deposit based on different column (disk) heights: M, K, and R are the same as in Fig. 3, only H is varied.
