Radiance Values for Translucent blinds

Hi,

Im inputting a material for a translucent blind that diffuses the light. And require information on what would be the best material setup in radiance. i thought it would be best to use a trans material but i dont know what typical specularity, roughness, transmisivity or transmittedSpecular values would be. As seen in the attached image I require all the values.Does anyone know the values that can be used in this case to represent a translucent blind?

In this case the red, blue and green transmittance is 0.05
