Estimates of timescales for ionisation (I) and recombination (R) equilibrium for Fe ix and Fe xii inside the model.
| Ion | Tmin ≈ 1 × 106 K | Tmax ≈ 1.1 × 106 K |
| ne, max ≈ 3 × 109 cm-3 | ne, min ≈ 2.7 × 109 cm-3 | |

||
| Fe ix | 2 s (I), 2.1 s (R) | 1.3 s (I), 2.1 s (R) |
| Fe xii | 22.5 s (I), 1.5 s (R) | 12.9 s (I), 1.5 s (R) |
Notes.The timescales are given in seconds and are calculated as 1/(ne × X(T)), where X(T) denotes either the ionisation or recombination rate obtained with CHIANTI assuming a Maxwellian distribution for the plasma. The temperature (T) and number density (ne) values used for the calculation are extreme values found in the centre of the cylinder.
