In the REIP operator there is an obvious error.
For Sentinel-2 the used formula is stated to be: 700 + 40 * ((B4 + B7)/2 - B5) / (B6 - B5),
which is valid for interpolation between 700 nm and 740 nm (as introduced by Guyot and Baret, 1988).
However, Sentinel-2 bands are at 705 nm and 740 nm, thus the formula must be:
705 + 35 * ((B4 + B7)/2 - B5) / (B6 - B5).

Hi Jan,
thank you for your report. I have just created an issue in order to check it.
