v16 v17 17 17 === Running Py6S for hyperspectral delivery check === 18 18 19 You can plot the at-sensor radiance spectra recorded by hyperspectral sensor and compare it to the at-sensor py6smodel using the script check_fenix_spectra_py6s.py. This procedure should be done during the hyperespectral delivery check.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.

Example: … … 35 35 check_fenix_spectra_py6s.py -i ./flightlines/level1b/ --num_plots 3 -o $output_folder 36 36 }}} 37 This will run the py6smodel 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.37 This will run the Py6S model 3 times for flightline and can take some time to complete.

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:
