An analysis of CDR Fravor’s encounter. (A). Truncated Gaussian distribution of Fravor’s visual acuity based on ${1/30}^{\circ }\pm {1/60}^{\circ }$. (B). Gaussian distribution of distances based on the visual acuity distribution in A. (C). The distribution of times based on $1\pm 1\mathrm{s}$. (D). The distribution of accelerations has a maximum at ${150}_{-80}^{+140}$ $\mathrm{g}$ (red lines) and a mean of $550\mathrm{g}$ (black dotted line).
