Comparison of theoretical and observed SEDs of Vega. Top: SEDs of Vega computed using 1D hydrostatic LHD (red dotted line)and ATLAS9 (blue dashed line) model atmospheres, plotted together with the HST CALSPEC absolute calibrated flux spectrum of Vega from the HST CALSPEC library (black solid line). The close overlap of the three lines makes it difficult to distinguish between them. Bottom: relative differences between the SEDs: HST CALSPEC – LHD (red dotted line) and HST CALSPEC – ATLAS9 (blue dashed line).
