In the published Letter, Table A.3 contains incorrect peak velocities of the N2H+ (3–2) and N2D+ (2–1) lines. This was due to a systematic shift of − 15 km s-1 applied to the central channel of the spectra during the observations (to avoid possible spikes at band centre), and not corrected at a later stage. This error only affected the values listed in Cols. 3 and 8 of the Table, and does not affect the other parameters derived from the fits, as well as any conclusion of the paper. The correct Table is included below.

Moreover, the names of cores G034-F1(MM8) and G034-F2(MM7) given in Tables A.1 and A.3 had been switched. The correct coordinates are: RA = 18:53:16.5, Dec = +01:26:10 for G034–F1(MM8), and RA = 18:53:19.1, Dec = +01:26:53 for G034–F2(MM7). Therefore, all parameters given in Tables A.1 and A.3 for G034-F1(MM8) were in reality for G034-F2(MM7), and vice-versa. We apologize for any confusion that may have occurred due to these mistakes.
