a Intensity distributions at 28 ms after impact within the area with N0 = 100 × 100 pixels: #532 (D = 0.85 mm, α = 2.0) (thin black curve) and #538 (D = 4 mm, α = 2.0) (bold red curve). b Cumulative number of pixels with an intensity lower than I, N(< I), normalized by N0: #532 (D = 0.85, α = 2.0) (thin black curve) and #538 (D = 4 mm, α = 2.0) (bold red curve). The horizontal broken lines indicate N (< I)/N0 of 0.9 and 0.1. c The ratio of the intensities at N (< I)/N0 of 0.9 and 0.1, I90/I10. The horizontal axis is the normalized time τ, i.e., the time after the impact t divided by the characteristic crater formation time t0 = 100 ms
