Variables derived from the magnetogram and Hα spectroheliogram analysis.
| Variable | Definition |
|
|
|
| Npil | Number of PIL pixels on each image |
| Duni | Distance between the current PIL pixel and the closest unipolar area (Mm) |
| Auni | Size of the closest unipolar area to the current PIL pixel (fraction of solar hemisphere) |
| ∇Bpil | Gradient of the magnetic field at the PIL pixel location derived from the smoothed map (G/Mm) |
| Dfil | Distance between the current PIL pixel and the closest filament (Mm) |
| Dpil | For each filament, distance to the closest PIL pixel (Mm) |
|
For each filament, distance averaged over the filament to the closest PIL pixel (Mm) |
