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 L. Robinson (lead).
MPB 29, 6-7: P = 6.442, A = 0.38, U = 2. Remeasured images using 2MASS conversion found new period, which are similar to P = 8.2 h reported by Behrend.
