Cristallina data analysis modules and plotting utilities.

This is a python package for data analysis, plotting and utility functions for the Cristallina endstation @ SwissFEL.

The data analysis is based on the common SwissFEL data architecture, with convienent access provided by sf_datafiles. Some parts require access to SwissFEL-specific data storage but the aim is to use this package indepedently for data analysis both online and offline operation.
