Microstability of Beta sim 1 Tokamak Equilibria (Erratum)

The published article incorrectly contains a placeholder reference to an equation (“(2.2)”) on page 2, paragraph 2, line 4:  “The high-beta, β ∼ 1, regime has been explored previously in the context of asymptotic magnetohydrodynamic (MHD) equilibria by solving the Grad–Shafranov equation in the limit ε/(βq²) << 1 (Hsu, Artun & Cowley 1996) where ε is the aspect ratio of the tokamak and q is the safety factor defined in (2.2):.”
