Observations are shown with symbols, thick full line corresponds to the synthetic spectrum calculated with the best-fitting stratified abundance distribution and dashed line shows prediction of the spectrum synthesis with a homogeneous abundance.

Figure 9:

Observed and theoretical energy distribution of HD 101065 calculated with scaled REE opacity from ISAN line list (see text). For comparison purpose the theoretical energy distribution of a normal F-type star HD 49933 is also shown. All theoretical calculations are smoothed with 20 Å Gaussian. Theoretical fluxes were scaled assuming radiuses: $R=1.98~R_\odot$ for HD 49933 and $T_{\rm eff}=6400$ K models; $R=1.90~R_{\odot}$ for $T_{\rm eff}=6500$ K; $R=1.82~R_{\odot}$ for $T_{\rm eff}=6600$ K.
