As Fig. 11 but with a different normalization to emphasize the differences between extinction laws. In each case we have subtracted a linear fit A(λ)/A(5495 Å) = a(R5495) + b(R5495)x, with a(R5495) and b(R5495) calculated so that the CCM law for that R5495 is 0.0 at x = 1.1μm-1 and at x = 3.3μm-1, the limits for the optical range in CCM.
