Increasingly X-ray-damaged room-temperature data sets from single crystals of thaumatin, proteinase K and lysozyme. Each point represents a complete data set of 120 images that was collected with the same crystal orientation (referred to here as a sequential X-ray-damaged data set; see Section 2). (a) Normalized data-set intensity, (b) data-set resolution and (c) unit-cell volume as a function of the absorbed X-ray dose [average diffraction-weighted dose (DWD); see Section 2].
