“…The parameters to obtain these results are summarised in Table 1 and it is clear that: 1) the diffusion was required to continually increase from 2006 to 2009, with the value of κ ||,0 increasing from 16.0 in 2006 to 17.1, 17.5, and 19.4 in 2007, 2008, and 2009 respectively; 2) the spectra became progressively softer towards 2009, so that the rigidity dependence of the diffusion coefficient below ∼ 3 GeV was required to change from P 0.85 in 2006 to P 0.81 , P 0.78 , and P 0.73 2007, 2008, and 2009. These type of changes are in agreement with those found by various other authors, including Bazilevskaya et al (2012), Ndiitwani et al (2013), Potgieter et al (2014), and Pacini and Usoskin (2015). Except for providing evidence for the applicability of the SBM in particular, this qualitative correspondence in modulation results over the entire solar minimum period of 2006 to 2009 also illustrates the already well established credibility of the SDE-based model.…”
