We compute V_PTF model magnitudes by first assigning fixed A_bond and G₁₂ values to each GALEX-observed asteroid depending on its color class; we then use D to compute H, and finally use the assumed G₁₂ value to predict V. The fixed values of A_bond and G₁₂ are medians from the color-albedo-G₁₂ data in Waszczak et al. (2015), 2D histograms of which are shown here. Above each plot is the sample size (N = …). A total of 642 asteroids have color data and G₁₂ values in the PTF data; 355 of these also have diameters available (required to compute A_bond). Panel (D) shows that WISE W1 geometric albedos correlate with the PTF bond albedo; we thus use the WISE p_W1 data to assign C types either a low (A_bond ≈ 0.01) or high (A_bond ≈ 0.04) bond albedo.
