Natrolite - NanED Round Robin, Data: ESR14 & ESR15

Natrolite

The following submission contains the data collection and processing for the sample Natrolite under the NanEd round-robin project.   Many crystals were identified, and data were collected using the continuous rotation data acquisition technique. All the data sets were processed with Dials software. The table below summarizes the data collection parameters.
