    5353=== Checking the spectra===
    54 The Py6S model selected for this simulation has no atmospheric correction and should have always higher values than the spectra measured by the Fenix instrument.
     54The Py6S model selected for this model is simulating at-sensor radiance for a given plane altitude but has no atmospheric correction for specific areas. The values of spectra recorded by the Fenix instrument may differ from the Py6S model (due to humidity, aerosols, etc.) but will always have the same features of absorption-reflection for a vegetation pixel.

    5656Py6S has several parameters needed to run the model. For this script, ARSF have selected the most convenient ones for our use but do not expect perfect match of the hyperspectral spectra recorded from our sensor against the Py6S. A more detailed explanation about Py6S parameters and [wiki:Processing/Py6S_vs_Hyperspectral/Py6SParameters settings used by ARSF can be found here.]
