Reconstructed Lyman-α irradiance based on ISNv2 (red) and CEA17 (black) inputs. Also shown are the SATIRE-S Lyman-α reconstruction (Chatzistergos et al. 2025a, orange), and the observational composite by Machol et al. (2019, blue curve) with its uncertainties shown in light blue. The shaded grey area marks the period when the F30 data were used by Machol et al. (2019) instead of direct measurements. All series are shown as annual running means.
