Corrected absolute magnitude (H; P. Pravec et al. 2012) vs. NEATM-derived geometric albedo (p_V) for the Koronis family (this work) and Karin cluster (A. W. Harris et al. 2009). In the left panel, large (13 < H < 14; orange; N = 23) and small (16 < H < 17; blue; N = 12) Koronis family members are shown along with remaining Koronis targets (black; N = 42) that fell outside of the designated size populations and Karin cluster members (gray; N = 16). The middle panel shows histograms of p_V for Koronis (black) and Karin (gray) populations, with solid horizontal lines indicating mean values and solid vertical lines representing the 1σ uncertainties. The right panel shows p_V histograms for large (orange) and small (blue) Koronis family targets. The full Koronis sample has a mean albedo of p_V = 0.24 ± 0.12. Large and small subpopulations yield mean p_V values of 0.23 ± 0.06 and 0.32 ± 0.18, respectively, with no statistically significant difference (K-S test: D_K-S  =  0.457, p = 0.043). The Karin cluster shows a mean p_V of 0.22 ± 0.05, consistent with the Koronis family distribution (p_V = 0.24 ± 0.12).
