Description

left-over from #501 :

some of the VI's defines in the awsome package need CONSTANTS --> these have to be added to the approach and should be loaded from [constants.json]
Note: the CONSTANT lambdaG, lambddaN and lambdaR have to be filled by the specification of the sensor (center wavelength of the band of the used satellite)

Direct constants are supported since f19ab24c695bd9c7180208a00b06d9c577291e7e

However, the sensor-dependent constants are not supported yet

Research direction

Start by reviewing the approach described in #501, constants.json, and commit f19ab24c695bd9c7180208a00b06d9c577291e7e to understand how direct constants are loaded. Identify how the sensor specification exposes band center wavelengths, then verify that sensor-dependent constants are handled for the affected spectral indices.
