Epidote - Sample 1 NanED Round Robin, Data: ESR10

Epidote

The following submission contains the data collection of datasets for the sample epidote under the NanEd round-robin project. 5 single crystals were identified, and the continuous rotation data acquisition technique was used to collect datasets. All the datasets were processed with REDp, XDS and shelx software. The table below summarizes the data collection parameters for the datasets. The following data is also in the zip folder as a word file.
