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

MPB 30, 61-64: P = 8.90, A = 0.25, U = 2.

Remeasuring the images to calibrate sessions found the slightly longer period but not significantly improved solution.
