NOTES: |
Unless otherwise stated, the "Reduced Magnitudes" in the plots are
Cousins R, based on 2MASS to BVRI conversions (Warner, MPB 34, 113-119)The data from Sep 14 cover more than a cycle. However, the 3-day gap between sessions allows for rotational aliases. The period is in good agreement with Harris (1999) and Pilcher (2000).
Collaboration with F. Pilcher and V. Goretti. Only PDO data are shown. |
