Natrolite - Sample 2 NanED Round Robin, Data: ESR4 & ESR5

Natrolite

The following submission contains the data collection and processing of datasets for the sample natrolite under the NanEd round-robin project.  A single crystal was identified, and continuous rotation and precession data acquisition techniques were used to collect datasets on the same crystal.  All the data sets were processed with PETS2 software. The table below summarizes the data collection parameters for the data sets. The following data is also included as a text file in the data folder.
