Notes. We ran about fifty 3D high-resolution simulations of the SNR, exploring the space of parameters reported in Table 2; we summarize here only the models that best match the observations. (a)Presented in Wongwathanarat et al. (2017). (b)Presented in Paper I. (c)The shell is characterized by the best-fit parameters reported in Table 2 but with nsh = 10 cm−3 and ϕ = 0. (d)The shell is the same as in SH1 but rotated by 90° clockwise about the y axis. (e)The shell is the same as in SH1 but with density nsh = 20 cm−3 and ϕ = 50° (see Table 2).
