Standard disc structure before the inclusion of the MCZ effects. Left hand panel: surface density of the disc in g cm⁻² on a log scale plotted against the radius of the disc in units of the white dwarf radius. A small knee can be seen in the data at the location where mass is added to the disc at 0.9r_out. Otherwise the plot shows the expected power-law with an inner edge turnover. Right hand panel: effective (surface) temperature profile of the disc in Kelvin. The peak temperature is approximately 42 400 K. Overlaid in a red-solid line is the standard disc temperature profile taken from Table 8 of Linnell et al. (2007b). Overlaid in a green line is the adjusted temperature model of Linnell et al. (2007b) which is isothermal inside a radius of r/r_WD = 2.56.
