Description:
We analyse photometric observations of the young active dwarf AB Dor,
spanning more than 20 years, and including previously unpublished
data. The data in table2.dat was observed at Molehill Astronomical
Observatory (Auckland, New Zealand) by M. Bos using a 200mm f10
Schmidt-Cassegrain Telescope with standard Johnson B and V filters.
The data in table3.dat was observed by G. Cutispoto using the 0.5m
telescope at the European Southern Observatory (ESO, La Silla, Chile)
and the 0.5∼m SAAO telescope (Sutherland, South Africa) with UBV(RI)c
filters.
