✦ Synopsis
The limb-darkening data published by Neckel and Labs (1994) (5th-order polynomials Ps(#), # = cos 0) are used to represent the limb darkening by the functions Ln (#), proposed first by . When plotted against wavelength, the coefficients of these functions show a rather low scatter and appear to be linear functions of either A -1 or A -s.
