Mean contribution of Lyα, Ca II, and Mg II lines to the total integrated radiative losses (kW m−2) for the regions highlighted in Fig. 1.
| Spectral lines | Regions |
|||
|---|---|---|---|---|
| A | B | C | D | |
| Ca II H | 0.75 | 3.9 | 6.1 | 17.6 |
| Ca II K | 0.72 | 5.4 | 8.3 | 22.8 |
| Ca IR | 3.2 | 9.1 | 14.9 | 32.5 |
| Mg II h | 0.27 | 2.4 | 3.4 | 25.2 |
| Mg II k | 0.21 | 2.8 | 3.7 | 28.2 |
| Lyα | −0.17 | 0.3 | 0.76 | 7.05 |
| Total | 4.93 | 23.9 | 37.16 | 133.35 |
Notes. The Ca IR refers to the triplet: Ca II 8542, 8498, 8662 Å. A, B, C, and D regions correspond to the quiet-Sun, bright fibrils, pixels near the polarity inversion line, and footpoint pixels at the flare peak time, respectively.
