Table 3.

Possible average azimuth configurations for the erupted and stable filament areas within maps A and B.

Azimuth (°)
Erupted filament
Stable filament
Maps Q1 Q2 Q3 Q4 Q1 Q2 Q3 Q4
A and B 60 150 240 330 78 168 258 348
σ 11 14

Notes. Any combinations between quadrants Q1Q4 of the erupted filament and the Q1Q4 of the stable filament are possible. The dispersion associated to the average azimuth is given by the standard deviation σ.
