The diffuser reflectance, $R_d$, was measured with an integrating sphere at 351, 365\,nm and in the range 440--800\,nm. The lateral spread of light introduced by a 400\,mm optical fiber was measured and analyzed to yield the optical penetration depth $\delta$. The two measurements, $R_d$ and $\delta$ yielded the absorption coefficient $\mu_a$ and the reduced scattering $\mu_s'=\mu_s(1-g)$ at 351, 365\,nm and in the range 440--800\,nm.}, }
