Fractional difference between the reflected energy spectrum for a cloud model with mass M_B2 and a fraction f_DGMF of its mass found in clumps and a homogeneous cloud model with total mass M_B2 × (1 − f_DGMF), shown with a spectral resolution of 20 eV. The fractional difference is negligible for all energies, reinforcing the idea that the clumping of part of the cloud’s mass into very dense regions effectively “hides” that mass from incoming X-rays.
