Histogram of the computed slopes of the linear fits of the phase – magnitude for asteroids numbered from 1 to 10 000 (top right). The top right panel shows the same, but for objects numbered from 100 000 to 110 000. The bottom left panel shows the slope error vs. slope for asteroids numbered from 1 to 10 000 after those with values of the resulting linear correlation < 0.8 and/or a number of accepted transits < 8 were removed. The bottom right panel shows the same, but for asteroids numbered from 100 000 to 110 000.
