What are the radiometric characteristics of the merged 1A and 2A product?
The merged product is produced with the same radiometric range as the 10 m colour source product. The values of the additional radiometric data (PHYSICAL_GAIN, PHYSICAL_BIAS) are the same as those for the 10 m colour source product. All information which is no longer relevant has been removed (Pixel_Parameters, Dead_Detectors, Bad_Lines). However, since the objects were not observed using the same scale for both products, the spectral content may not be exactly the same (whence the slight differences in the histograms).
