    • In our previous paper [3] the gap function (diagonal element) of the 4th band had nodes intersecting the β Fermi surface. This was in fact due to a technical error in the final stage of the calculation, i.e., the unitary transformation from the orbital to the band representations. However, the main conclusions of Ref. [3] do remain unaltered, since (i) the magnitude of the gap along the β Fermi surface varies significantly as mentioned here, and (ii) the coexistence of (π, π/2) and (π, 0) spin fluctuations determines the way in which nodes appear as asserted in [3]. The nodes of the gap function do intersect for certain choices of the parameter values or a slight change in the band structure, as shown in Ref. [21].
