We used our results and the literature to plot the light-curve amplitude versus absolute magnitude distributions of the CC population and of the other TNOs. Different symbols and colors are used to separate the two populations and the partial/full light-curve sample. Two running means using the partial and the full light curves are overplotted, one for the CC population and one for the other TNOs. The other TNOs have a roughly flat distribution across the different size regimes, whereas the CC population is showing an increase of amplitude at small sizes. Some bins only have one or zero object.
