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

There were no indications of a long period seen in the PDO data by radar or independen observations. Its source is a mystery since the images were measured using 2MASS to BVRI calibrations and only solar-color comp stars.
