Correction performance in three spectral regions with strong tellurics.
| Data | Order 54 (10−3 RMSE) | Order 60 (10−3 RMSE) | Order 64 (10−3 RMSE) |
|---|---|---|---|
| Val Mol | 6.4 | 5.8 | 13.2 |
| Val TAU | 3.9 | 4.5 | 5.8 |
| 2015 TAU | 4.0 ± 0.5 | 4.8 ± 0.6 | 6.7 ± 1.3 |
| 2016 TAU | 3.9 ± 0.4 | 5.0 ± 0.6 | 6.6 ± 1.4 |
| 2017 TAU | 4.0 ± 0.5 | 5.0 ± 0.6 | 6.6 ± 1.4 |
| 2018 TAU | 4.2 ± 0.4 | 5.4 ± 0.6 | 6.7 ± 1.2 |
Notes. The order 54 tellurics lie in [5945.1 Å, 5946.3 Å], order 60 in [6289.0 Å, 6290.4 Å] and order 64 in [6543.5 Å, 6544.3 Å] with all wavelengths in observatory rest frame measured in air. Val Mol and val TAU are the performances for molecfit and TAU for the single 2020 validation spectrum. 2015 TAU, 2016 TAU, 2017 TAU and 2018 TAU are the performances for the annual observing seasons computed as the mean RMSE and standard deviation of the autoencoder residuals from 100 random solar observations from each year.
