Hi Yong Yes of course the _average_ resolution of the map, whether from single crystal or PD, is determined 'more or less' by the minimum d-spacing ('resolution limit'), in the same way that the _average_ quality of the agreement between the model and the data is related 'more or less' to the R fa

Ian, Won’t the spatial resolution of the electron density map be determined more or less by the “resolution” (d-spacing)? While the normal electron density includes model contribution, what about the resolution of the Patterson map? For the case of powder diffraction, after the lines are reso
