Correction of the degradation of the EUV component of LYRA channel 3. Same colors as in Figure 6: the red, dark blue and green lines show the simulated LYRA channel 3 and its EUV (λ > 17 nm) and SXR components (λ < 17 nm), respectively; the black and gray lines show the actual LYRA channel 3, corrected (by addition) and not corrected for degradation. The light blue curve shows the EUV component of channel 3 corrected for degradation by multiplication. The orange curve shows the whole LYRA channel 3 irradiance, with its EUV component corrected for degradation by multiplication. The start date for the use of the EVE data is indicated by the dotted vertical line.
