Variation in the balance between bright faculae and network and dark sunspots with solar activity. (a) The ratio , where ΣΦ_FN is obtained from the CJSS-YEA run, as a function of ΣA_S (crosses). As in Fig. 5, the annual mean over the period of 1924 to 1986 is depicted. The solid line follows the power-law fit (Eq. (22)) and the dotted line gives the position of the horizontal asymptote as given by the constant term in this fit. (b) The same, but for as a function of . The vertical dashed line indicates and the horizontal dashed lines gives the value of at and , as given by the power-law fit (Eq. (23)) (see Sect. 4 for details).
