CI-710s NDVI calculations
How the CI-710s internally calculated the NDVI values from measurements
The CI-710s uses the measurement values from all spectra that round up/down to the target value and it calculates their average NDVI value to report as the calculated value.
Note that based on the spectra recorded during measurement there can be from 1-3 values that round up/down. (2 values are used below.)
