TIP

In general, it is recommended to perform the DOS1 atmospheric correction for the entire image (before clipping the image) in order to improve the calculation of parameters based on the image.

Radiance values

You can check, either in the legend or using the i tool that every pixel has an integer value.

Look at the following example, from Sentinel-2 band 04. Pixel values are in the range of [235, 4877].
