The iron Kα fluorescent lines detected in several Seyfert 1 galaxies are usually explained as arising in the innermost regions of an accretion disk around a supermassive black hole. We present a method that allows to derive a free-form fit to the radial emissivity law in the disk. We find that most of the emission comes from quite narrow regions very close to the black hole. .
