Fig. 2.6 The changes of average slope of lunar surface according to the variation of baseline for
different topography
of slope is generally 30% of average slope; the second is that the maximum slope is
usually no more than 4 times of the average slope.
The cumulative distribution of slope of the smooth mare and the rough mare is
shown in Fig. 2.7. With the increase of slope, the variation of cumulative percentage
of area becomes slower, which means that the larger the slope, the smaller the
percentage. Besides, as the baseline increases, the maximum of slope becomes
