Comparison of inverse method and quadratic limb darkening for recreating stellar center-to-limb brightness variations. Black shows the specific intensity directly from the stellar model. The stellar model is taken from case 2 in Table 1 at λ = 0.850 μm. Red shows the recreation of specific intensity using quadratic limb darkening with coefficients ﹩{\gamma }_{1}=0.21﹩ and ﹩{\gamma }_{2}=0.45﹩. Blue shows the recreation of specific intensity using the method presented in this paper. Upper panel: direct comparison in a continuum wavelength. Lower panel: shows the difference between fitted specific intensity (blue or red in upper panel) and model specific intensity (black dashed line).
