The mark entered into A under the stave almost certainly concerns the A
minim; as such, it is a long accent, which we provide in the main text. In the editions it was reproduced as a 
hairpin, adjusting its range to the R.H. chords – in GE from the 2nd to the 4th chord. This version was reproduced by the remaining editions (except EE1, in which the mark was overlooked), FE being the least accurate.
