In the sources, there is no  restoring d1 on the 4th beat of the bar. The mistake resulted from the way the piano reduction was prepared – the R.H. top voice corresponds to the Violin II part, in which there is no need for a , since it does not feature a d1.

We consider the version of A (→GE1) to be erroneous, which is indicated by the orchestral part – an F in cellos and double basses is both in the later version of AsI and in the voices of GE and FE. The correct version of FE almost certainly resulted from Chopin's correction, probably introduced still into the copy of GE1 serving as the basis for that edition – there are no visible traces of changes in print. The corrections present in GE2 (→GE3,FESB) and EE2 (→EE3) can be considered revisions on the basis of orchestral parts. In the case of GE2, Chopin's intervention is also likely; his participation in the preparation of that edition is generally questionable, yet it cannot be excluded to a limited extent.
In the basic version of AsI, which is an earlier edition of this orchestral introduction, neither of these versions can be used.

h2 sustained in A (→GEFE,EE)

No prolongation in FESB

..

The b2 note, provided with a ten., is prolonged to a crotchet in A (→GEFE,EE). It seems to be Chopin's mistake, since such a long value would have to be held also at the beginning of the 2nd half of the bar, which would certainly be a mistake. To avoid doubts, we change it to a quaver, almost exactly corresponding to its actual length. The fact that FESB omitted that extension could have resulted from that erroneous notation, with which the engraver did not know what to do.

The  restoring b1 in the 2nd half of the bar is absent in all sources. It must be Chopin's mistake, one of his most frequent errors.

e3-g3 in sources, literal reading

e3-g3 suggested by the editors

..

Even though none of the sources features an accidental to the top note of the last semiquaver, the use of g3 is much more likely, considering the melodic and harmonic context. Overlooked accidentals in such situations are one of Chopin's most frequent mistakes, cf., e.g. the Etude in F minor, Op. 25 No. 2, b. 4 or the Impromtu in A, Op. 29, b. 3 and 71.
