Use a cut-of mask for the heatmap (black) so that only best areas are lit for less confusing look


Imagine seeing this for the first time and not knowing what it is. I need only well lit SNR places and the rest completely dark (black) to an idea of good SNR.

Look for the heatmap generation code, likely in a visualization or plotting module. Identify where SNR values are mapped to colors and apply a mask to set values below a threshold to black. Test by running the simulation to see the updated heatmap with only high-SNR areas lit.
