    • We note however that the original values of ξ and η in Eq. 4 must be rescaled by 10-2. However, since their precise values are uncertain, we do not include such a rescaling explicitly.

    • Notice that, within conformal field theory (Ref.), the Abelian sectors corresponding to the charge Q and the flavor Tz are labeled by an integer m defined modulo 4, e.g., m=-1,0,1,2. Therefore m=+2 and -2 have to be identified; they correspond in conformal field theory to the same character although physically to two different states. Seemingly, if we shift up by one the quantum numbers, then m=2, which is the same as m=-2 that transforms into m=-1.
