Erratum to: Line operators on S1×ℝ3 and quantization of the Hitchin moduli space

We thank Daigo Honda for pointing out this error. We note that in terms of Θ := Θ − θRA (∞) τ , we can also write b = Θ 2π − 4πiR g Φ (∞) 9 + θ 2πa, an expression more similar to the one before correction. The meaning of Θ can be understood by carefully performing dimensional reduction and 3d abelian duality: 2πRA (∞) τ and Θ are the vevs of linear combinations of scalars that diagonalize the kinetic terms. In addition, the second line of equation (6.15) should be replaced by
