The pedalling was added in a proofreading of FE (→GE,EE). The omitted 
mark closing the pedal from bar 53, probably by mistake, was completed in GE. In the main text we suggest the same solution. The 
mark in bar 53 is written in FE (→EE) under the rest. According to us, it is the notation's inaccuracy, therefore, in the main text we move the sign one quaver later. Alternatively, it cannot be excluded that according to Chopin's intention, the pedal should be depressed at the beginning of the bar.
