Slope, correlation coefficient (r), and reduced chi-square (
) between the modeled and observed total magnetic flux (TMF) and TSI, and between the modeled UV (220–240 nm) irradiance with SATIRE-S and SATIRE-T2, for different averaging periods.

Notes. Note that only the total magnetic flux and the TSI are used to optimise the SATIRE-T2 model.
Reduced chi-square of SATIRE-T2 following the definition used by Krivova et al. (2010).
