$^a$~Units are: TSI (Wm$^{-2}$), the open field at 1~AU ${B_{\rm R}}$ (nT), SSN (number), F10.7 (sfu $\equiv$$ 10^{-22}$~Wm$^{-2}$~Hz$^{-1}$), Ly-$\alpha$ (mWm$^{-2}$), CaII~K and MgII indices (core-to-wing ratio). The amplitudes are equivalent sine-squared in units of the parameter, and the trend during each cycle is removed.
