NOTES: Unless otherwise stated, the "Reduced Magnitudes" in the plots are Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)

PDO binary discovery in collaboration with Petr Pravec's Binary Asteroid Survey group. Lower limit of Ds/Dp = 0.38 (meaning the satellite has an effective diameter of at least 0.38 that of the primary). This is somewhat larger than usual.
