Fig. 6From: Discrepant responses of the global electron content to the solar cycle and solar rotation variations of EUV irradianceScatter plots of GEC365A versus EUV365A (a) and GEC27R versus EUV27R (b). Solid lines are the liner fittings of the dots, and the corresponding fitting equations are printed in the top of each panel; the parameter r is the correlation coefficient between GEC and EUV. The dominative 1-day lag of GEC27R to EUV27R is taken into account in b Back to article page
