I would like to perform atmospheric correction on WorldView-3 8-Band VNIR MSI. I found a radiance response file here: https://git.orfeo-toolbox.org/otb-data.git/tree/HEAD:/Input/Radiometry/DigitalGlobe. However, I do not think it is in the correct format. I believe what is expected is for the first column to be wavelengths in microns (not nanometers), the second column should be solar irradiance (not provided in the file), and the next columns are the spectral responses for each band. I think I can use the Thuillier 2003 spectral response curve listed here: https://dg-cms-uploads-production.s3.amazonaws.com/uploads/document/file/207/Radiometric_Use_of_WorldView-3_v2.pdf, but I'm not sure what order the bands should be listed. The provided file has PAN, C, B, G, Y, R, RE, N1, N2, S1, S2, S3, S4, S5, S6, S7, S8. I think since I have just the 8-band VNIR product that I should have them in C, B, G, Y, R, RE, N1, N2 order with the others excluded from the file, but I'm not sure. Also, what units should the spectral response values be in? The provided file has them as radiance values.
