29. These values themselves are not so important. Qualitative results in this paper do not change, as far as we can reproduce the band structure near the FS.

33. ℓm(k). Although we show the sum of the third- and fourth-band for want of space, they have large weight on the different FSs.
34. To examine the case with the large outer FS, we here show the result at n = 6.00 not electron-doped region. The magnitude of gap around Γ′ changes dependent on carrier doping. It is ∼-0.5 in the hole-doped and ∼1 in the electron-doped.
35. Increase of eigenvalues around hole-doped n ≃ 5.80 comes from change of the Fermi surface due to the self-energy shift. It probably does not reflect the real fact in this system.
36. ±-wave state has the largest eigenvalue. At a glance, this seems to be inconsistent with the result in ref. 25. This is probably because of different dispersion relations, especially, size of the FS around Γ′.
