We present a numerical, maximum entropy technique for reconstructing the distribution of dust mass as a function of temperature from a set of thermal continuum fluxes. The particular formulation used can accommodate an arbitrary wavelength dependence of dust emissivity, but does require the emission to be optically thin. The dust emission spectrum of the M175W molecular cloud is analysed, assuming a dust emissivity κν ∝ ν2, and the resulting dust temperature distribution is found to differ markedly from that predicted by the analytical inversion technique of Xie et al.
