Limb darkening

Linear limb darkening coefficients are taken from tables published by Van Hamme (1993, AJ 106, 2096).

limb_stars Compute limb darkening fit coefficients for all stars.
limb_star(spectrum$<$_char$>$,filter$<$_char$>$)

Function. Return linear limb darkening coefficient integrated over specified bandpass. Example: print, limb_star('G0I','V').

limb_filter(teff$<$_real$>$,log(g)$<$_real$>$,filter$<$_char$>$)

Function. Return linear limb darkening coefficient integrated over specified bandpass. Example: print, limbfilter(5500, 0.5, 'R').

limbband(teff$<$_real$>$,log(g)$<$_real$>$,center$<$_real$>$, width$<$_real$>$)

Function. Return linear limb darkening coefficient integrated over band pass with specified center and full width (in nm). Example: print, limbband(5000, 0.5, 700, 25).

limbfactor(coeff$<$_real$>$)

Function. Return factor to multiply the uniform disk diameter with in order to get a limb darkened diameter using the specified linear limb darkening coefficient. Based on the squared visibility matching at 0.3 and a formula derived by Hanbury Brown (1974, MNRAS 167, 475).
