Top panel: comparison of our computed solar disc centre continuum intensity in the non-magnetic and 200 G case (solid black and red curves, respectively) to data from the literature. The long-dashed curve is based on the results obtained by Trujillo Bueno & Shchukina (2009) using a single 3D HD snapshot by Asplund et al. (2000a); the dotted curve with circles is based on Ayres et al. (2006); the short-dashed curve refers to the semi-empirical 1D MACKKL model of the “quiet” Sun atmosphere (see Table II of Maltby et al. 1986); finally, black crosses indicate the observational data from Neckel & Labs (1984, Table VII). Bottom panel: intensity difference (in percentage) between our results and the observational data (black crosses = HD-obs; red crosses = 200 G-obs; dashed horizontal line = –5% level).
