Typical V-band time series collected by the ASAS survey. The red and green bullets mark the segmentation performed by Messina et al. (2010). The black continuous boxes depict two of the extracted segments, while the dotted box indicates one of the sub-series rejected by our segmentation algorithm. The black crosses mark data that have not been processed in Messina et al. (2010). We employed a 50-day sliding window, while in the plot we sketch a 200-day sliding window for clarity.
