Measurement of the mass distributions in the decays D0→K−π+π0, D0→K0Sπ+π−, D+→K0Sπ+π0 and D+→K−π+π+. The data were read from the plots in the paper. Resolution/acceptance effects have been not unfolded and given the agreement with the model in the paper this analysis should only be used for qualitative studies.
