SED measurements of DoAr 44 and a synthetic SED, made up of several components. The central star and accretion region dominate in the ultraviolet and visible range, and the outer disc is dominant in the sub-millimetre and millimetre wavelengths. These two contributions are well constrained from VLTI and ALMA interferometry. However, if only these two components are considered, a large deficit is present in the mid-infrared range. Therefore, an intermediate region must be present. The error bars are not visible, as the vertical axis spans ten magnitudes.
