Comparison between the Hα line-center visualization technique used in the current 3D WPFS models and the SOT-like Hα visualization that includes the Hinode/SOT NFI instrumental effects. In all panels, we show a detailed view of the GDASH model. In the top row, we display the synthetic images in Hα line-center and in the bottom row the synthetic SOT-like Hα images. In the left column, we plot intensities in the linear scale and in the right column in the logarithmic scale. All intensities are plotted in an identical color scale in units of erg s⁻¹ cm⁻² sr⁻¹ Hz⁻¹ (top row) and digital counts (DC, bottom row). Dimensions are expressed in arcsec.
