Observed median SED of brown dwarfs in Chamaeleon I (diamonds), where the 24 micron and millimeter point should be treated as upper limits. Overplotted is our best-fit disk model with a turbulent mixing strength of α = 10^-4 (solid line). Also plotted for comparison is a model with α = 10^-2 (dotted line). The dashed line denotes the stellar photosphere. The inset shows the millimeter regime.
