Vertical structure of temperature, density and dissipation heating rate defined by Eq. (22) for a sample of models computed according to the method described in Sect. 3.4. The first row shows the complete sample of models, while the second row only shows models that do not exhibit density inversion discussed in Sect. 2.4. Zones where TI occurs are omitted, which produces the gaps that are visible in many models. The color of the line corresponds to the magnetic gradient, q, (red is stronger field, blue is weaker), while the thickness shows the accretion rate ṁ (thicker is higher). The gray vertical lines show the optical depths τ equal to (from left to right): 100, 10, 1, 0.1, and 0.01.
