Comparison of effective collision strengths of S11+ for all excitations between levels of the n = 2 complex at three different temperatures log Te(K) = 6.04, 6.40 and 6.87. ΥICFT refers to the present ICFT R-matrix calculation, and KKR02 corresponds to the previous R-matrix results by Keenan et al. (2002). A few transitions with large difference are marked by labels around the points, and are linked together for results at different temperatures. (Colour online.)
