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

Collaboration with Robert D. Stephens of Santana/GMARS Observatories (lead on MPB paper).

The paper gave a period of 11.7 h. The actual period is half that, or 5.86 h. The plot uses on PDO data and was phased to a best fit period near the true period.
