Set of cuts for removing events produced by charged particles and during solar flares.
| Parameter | Expression |
|---|---|
| Number of pixels | > 70 + 30 × E/(1keV) |
| Energy fraction | < 0.8 × (1−exp(−(E/(1keV)+0.25)/1.1)) + 0.004 × E/(1keV) or > 1 |
| Border pixels | > 2 |
| Photon energy | > 4 keV |
| Radial distance | > 5′ |
| Count rates | > 3σ above the mean count rate |
| Time intervals | Flare 1 (DU 2), Flare 2 (DU 2 & DU 3), Flare 3 (DU 2 & DU 3), Flare 4 (DU 2 & DU 3) |
Notes. The polarization analysis does not use the events satisfying either of these expressions.
