Helium signature strength based on different techniques. The signal integrated over a 0.75 Å passband is the technique chosen in this paper.
| Technique | Excess absorption |
|---|---|
| Maximum absorption [%] | 4.02±0.24 |
| Integrated 0.75 Å passband [%] | 3.17±0.05 |
| Integrated 1.00 Å passband [%] | 2.81±0.05 |
| Gaussian fit [%] | 3.48±0.10 |
| Equivalent width [mÅ] | 49.18±1.22 |
