            <Description>Wave power values: E_pow_f4, E_pow_f5, E_pow_f6, E_pow_su and E_var_ts, are related to recording of natural wave emissions.
Those parameters, not affected by variations in instrument's transfer functions, are globally OK.
However, two factors can affect the precision of the measurements:
a) the occasional presence of spurious emissions created by operations of the EDI instrument increases the wave power values measured on SC1, SC2 and SC3, from an unknown amount,
b) the limited dynamical range of the instrument leads to an underestimation of the E_pow parameters values when the voltage difference measured by the double sphere antenna signal in the 2 - 80 kHz band is higher than 150 mVp or 600 mVp (depending of the gain chosen). As a consequence, high values have to be taken with special caution.
