Guillaume, I didn't know there were some files there with other formats. When we introduced the radiometric corrections in OTB, we decided to use the 6s format which I described in my previous message. This is why most of the files are called rep6s.dat. The files which do not follow this format are for Ikonos, Quickbird and WorldView 1 and 2. And the difference is not only on the lack of solar spectrum, but also in the units for the wavelengths. I don't know how are the radiometry tools parsing these files, but it seems suspicious to me that radiometric corrections can be done without solar spectrum information.
