15. 3 [3]: calculated for a purely 1D system, it should be compared not to the lowest gap (∼ 23 K) but to an "average gap", the averaging being made over the dispersions transverse to the chains [14].

25. In the I phase, we do not expect important changes for the local magnetization from the interchain couplings. They will, however, reduce the gap values as they do in the D phase [14].
