    19 You can plot the at-sensor radiance spectra recorded by hyperspectral sensor and compare it to the at-sensor py6s model using the script check_fenix_spectra_py6s.py. This procedure should be done during the hyperespectral delivery check.

    21 The simplest version of the script looks for a random vegetation pixel at nadir and plots its spectra recorded by the Fenix sensor versus the predefined py6s vegetation type without atmospheric correction.

    2323Go to delivery project directory that you want to check. Example:
     
    3535check_fenix_spectra_py6s.py -i ./flightlines/level1b/  --num_plots 3 -o $output_folder
    3636}}}
    37 This will run the py6s model 3 times for flightline and can take some time to complete. It will create 3 .png files per flightline that you will need to check carefully. To this end, you can find some essential tips on the bottom of this page.

    3939The script also needs the IGM directory and the NAV files for every file on the level1b directory. If the location is not the usual one and the script can't find it, you can specify their paths on the command line by using:
