In A Chopin wrote only one cautionary accidental before this chord – a  to e3. GE (→FE,EE,IE) also added a  to e2, which we include in the main text. See also the note above.

No c3 in IE

c3 with  suggested by the editors

..

It is difficult to say why the c3 minim is absent in IE. An oversight seems unlikely; therefore, it could have been a revision that omitted this note due to analogous bar 202 and the presence of only 4 slurs combining this chord with the next one. In the main text we include the note, clearly written in A, and add a cautionary  to it.
