NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)Two periods found in 2005. The shorter period is about the same but the longer periods differ considerably.
Data from 2011 indicate a period of 86 h. The U rating has been reduced to 1 because of the widely divergent solutions. |
