A configuration set is a subset of configurations that share some characteristic.
These may be defined for configurations containing certain elements, created by distinct methods, representing distinct crystal types, etc.
If an untarred file contains no cs and cs_co_map directories, no configuration sets have been defined for the dataset.
The following table provides a description of the columns found in untarred dataset parquet downloads.
Location: <dataset-id>/cs/*.parquet
