+Regarding the detection of shadows, the algorithm has been developed to identify only the shadows of clouds on the ground but some misclassification can occur. Often shadows and water have in fact similar reflectance 
 values which can lead to erroneous classification of water bodies as shadows. Therefore, in order to increase the accuracy of 
 the final shadow mask, a control check is implemented. Clouds and shadows are spatially intersected in order to remove misclassified areas.

+The algorithm works on reflectance values (Bottom of Atmosphere Reflectance) therefore the atmospheric correction has to be applied to all input bands (see <a href="i.atcorr.html">i.atcorr</a>)
