Epidote - Sample 1 NanED, Data ESR1 & ESR2

The following submission contains the data collection frames for the sample Epidote under the NanEd round-robin project.  Precession Electron Diffraction (PED) was carried out on a single crystal. The datasets were processed with PETS2 software and refined kinematically and dynamically using Jana. The table below summarizes the data collection parameters for the data sets.
