LINEAR AND NONLINEAR LIMB-DARKENING COEFFICIENTS FOR THE PHOTOMETRIC-BAND-R PHOTOMETRIC-BAND-I PHOTOMETRIC-BAND-J PHOTOMETRIC-BAND-H PHOTOMETRIC-BAND-K

We have computed limb-darkening coefficients for five commonly used ne ar infrared photometric bands, namely R, I, J, H, and K, using the ste llar atmosphere models by Kurucz (1991). Since the behaviour of the sp ecific intensities is very dependent on the range of effective tempera tures considered, we have adopted three analytical approximations to t he limb darkening: linear, quadratic and square root. The least-square s method has been adopted for the fit of the limb-darkening coefficien ts to the model atmospheres.
