Top: solar limb-darkening functions (LDF
at 607.1 nm) obtained with several values of the Fried parameter compared to the Neckel 2005 empirical solar model without atmospheric turbulence. Bottom: first derivative of the solar limb-darkening functions (LDF
at 607.1 nm) and location of the inflection point position of the solar limb-darkening function (observed solar radius).
