Ask for the calculating of reflectance #202

Thanks for your great contribution to multispectral camera development. I have a question. When I learn the "Tutorial 3 - DLS Sensor Basic Usage", I saw in the text that you wrote the calculating of reflectance is "divide pi times the irradiance by the radiance", like this "output = (π×irradiance)/radiance", but I saw in the micasense boxtool that you calculate irradiance_mean by the function: (radiance_mean × π) / reflectance, Is it right?And why? image image
