Notes.The centroid of all fits was fixed to the position of the dust continuum peak.
The radius perpendicular to the outflow as derived from the HWHM of the fit with fixed PA along the outflow.
The dust temperature at the radius perpendicular to the outflow was determined using the profiles calculated by Kristensen et al. (2012).
