Evolution of RV_S (middle) and θ₀ (bottom) along the B-LC (top) of the 2006, 2008, and 2009–10 outbursts. Maxima of 2006 and 2009–10 events are denoted by vertical bars. Uncertainties in RV_S and magnitudes are within the size of points, and those in θ₀ are described in Section 3.4.1. Data are from Burmeister & Leedjärv (2007), Tomov et al. (2007), Skopal et al. (2009), and our Table 2.
