The slur could have been added by Chopin in the proofreading of GE1 (→FE→EE), however, even if it was so, it is hard to assume that he wanted to embrace with it only a part of the bass's motif. In the face of doubts concerning the authenticity of both the slur as such and its range, in the main text we do not include this sign. In turn, we suggest a slur embracing the entire sequence of bass in this bar as an acceptable variant. See also the note on 
the hairpin.
