UDI Heat map LBT 1.3.0

Hello everyone!
I am working on UDI and I connect the values to a heat map component, I get a map as follows:

UDI

Are the colors of the heat map correct? the points away from the aperture have the highest values! Am I getting the concept of UDI wrong?

This is my script.

Hey @Ahd,

The lower UDI near the aperture is likely due to the upper UDI threshold being exceeded.

This website has a good explanation - note I think the ladybug tools default is an upper threshold of 3000lux
