Summary of features distinguishing the clusters under the various classification schemes tested.
| Class. Scheme | Cluster 1 | Cluster 2 |
|---|---|---|
| SVD Hellinger | Largest β, βγ sunspots; majority of βγδ; high concentration of patches with average magnetic field value ≃ 0; large Hellinger distance between ARs | Smallest β, βγ sunspots; high concentration of patches with average magnetic field value close to +1 or −1; small Hellinger distance between ARs |
| NMF Hellinger | Largest α, β, βγ sunspots;majority of βγδ; large Hellinger distance between ARs | Smallest α, β, βγ sunspots; small Hellinger distance between ARs |
