Heat maps of ΔT and Δβ measured on a simulated edge-on galaxy at various angular distances θ from the centre, as a function of the kernel type used. Each panel represents a scenario from Table 1. Dashed lines indicate the scale height of the dust profile zd. This figure highlights the very small scatter in both ΔT and Δβ when using the kernels with effective PSFs (column E on each plot, until the S/N becomes to low as in panel b.2).
