Radial cut of the temperature distribution of the dust around IRS 9A. The picture displays the temperature profile of the disk and the envelope obtained with our best radiative transfer model. The axis is given in spherical coordinates (R, θ) and the colors represent different temperature values of the dust. Also, confusion with other (extended or stellar) sources in the crowded IRS 9 region may be an important source of bias in the SED at certain wavelengths.
