Magnetopause standoff distance with respect to (a) the SW density (fixed v = 350 km s⁻¹), (b) SW velocities (fixed 12⋅ cm⁻³), and (c) dynamic pressure. Sun–Earth IMF orientation with |B| = 10 nT. The pink stars indicate the magnetopause standoff distance if |B| = 0 nT. The dashed lines indicate the data fit to the expression R_sd∕R_E = An^α, R_sd ∕R_E = A|v|^α, and . The solid red line indicates the fit line for the data set with n ≤ 60 cm⁻³ and |v| ≤ 600 km s⁻¹. The solid blue line indicates the fit line for the data set with n > 60 cm⁻³ and |v| > 600 km s⁻¹. The solid pink line indicates the fit line for the data set with n ≤ 60 cm⁻³ and |v| ≤ 600 km s⁻¹ and no IMF.
