QUASR: the QUAsisymmetric Stellarator Repository

This is a dataset of approximately 200,000 vacuum field stellarators along with the electromagnetic coils that generate them. The devices in the database are available in a couple of formats (SIMSOPT, VMEC) useful to the stellarator community. typo in uploads v1, v2: the 'total_coil_length' and 'coil_length_per_hp' keys in dataframe should read 'total_coil_length_threshold' and ''coil_length_threshold_per_hp'', i.e., the maximum allowable coil length and maximum allowable coil length per half period, respectively. v2 (January 29, 2024): additional QA devices added. v1 (October 29, 2023): initial upload.
