    Hi Luiz, the RapidEye Analytic OrthoTile pixel values have already been converted into radiance W/(m^2*μm*str) from DN values. The scaling factor is applied so that the resultant single DN values correspond to 1/100th of a W/(m2*sr*μm). The same scaling is applied to all bands.The conversion is done using the following formula:RAD(i) = DN(i) * radiometricScaleFactor(i), where radiometricScaleFactor(i) = 0.01The resulting value is the at-sensor radiance of that pixel in watts per steradian per square meter (W/m2*sr*μm). You should be able to take the Lmin and Lmax values without any additional calculations. All of this information is available on pages 30 and 31 of the Product Specifications Guide.
