Vertical temperature cut at a radius of ~50 au. Left: Fiducial envelope-plus-disk model with varying envelope masses and thus various mass accretion rates. Right: same as in the left panel, but for the fiducial models with large κ_{dust, mm}· The z of ~50–60 au marks approximately where the outflow cavity wall and hence the highest z at the disk or envelope surface at a radius of ~50 au is reached.
