Active longitudes: Phases of the spots on AB Dor. Filled circles denote primary spots, open circles secondary spots and the + symbol is used when it is not possible to say which spot is the primary one. Two active longitudes are traced by solid lines and the vertical dashed lines show when flip-flops occur.
