Reduced χ2 values between the model output and the comparison datasets.
| Parameter | This study | Krivova et al. (2021) | ||
|---|---|---|---|---|
| ISNv2 | CEA17 | ISNv2 | HoSc98 | |
| χ2 TF | 0.069 | 0.064 | 0.058 | 0.058 |
| χ2 OSF | 0.321 | 0.322 | 0.389 | 0.219 |
| χ2 TSI | 0.074 | 0.079 | – | – |
Notes. The comparison datasets are the total magnetic flux measured in ground-based magnetograms, the independent empirical reconstruction of the open solar magnetic flux, and the TSI measurement composite; see Sect. 2.2 for data description. Columns 1 and 2 list the results for the reconstructions using ISNv2 and CEA17 sunspot number series as inputs. Columns 3 and 4 are the corresponding results from Krivova et al. (2021). Note that their χ2 values of OSF refer to comparisons with the annual OSF reconstruction of Lockwood et al. (2014).
