These are data described in the paper "The brittle boulders of dwarf planet Ceres" by Schröder et al., submitted to the Planetary Science Journal. The data concern boulder counts for craters on the dwarf planet Ceres. Boulder counts for all 58 craters in Table 1 of the paper are provided as text files with 3 columns: (1) longitude and (2) latitude, both in degrees, and (3) boulder diameter in meters. Generally, boulder identifications are only reliable above 3 image pixels (105 m), but the data files contain all boulders that we (tentatively) identified, including those smaller than 105 m. We also provide figures in PDF format, one for each crater, of the spatial boulder distribution. The figures have the format of Fig. 12 in the paper: Green, small dots represent boulders with a size between 3 and 4 pixels (105 m < d < 140 m). Red, large dots represent boulders larger than 4 pixels (d > 140 m). Boulders smaller than 105 m are not shown. The coordinates in degrees of latitude and longitude of all craters in Table 1 are provided as a text file.
