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. Only PDO data are shown.

The "dips" orbital curve are due to occultations and/or eclipses involving the satellite. The "bowing" in the orbital curve is the result of the elongated satellite rotating at the same rate as the orbital period, i.e., it is tidally locked to its orbit.
