Project M: Calcium Carbonate Diffraction Datasets With Fit and Parameter Data

Project M (https://www.diamond.ac.uk/ProjectM/) was a citizen science initiative run with UK secondary schools that generated an open collection of more than 650 calcium carbonate diffraction datasets, crystallised under a wide range of additives and conditions, with all associated fits and parameters included. These records are hosted as a PSDI Community Data Collection and contain the raw X ray powder diffraction data from Diamond Light Source, accompanied by the essential experimental metadata.
