the slope of the straight line representing the best fit to the calibration values determined by the method of least square within the channel amplitude class
Calibration factor of a data channel
The mean value of the sensitivity coefficients evaluated over frequencies which are evenly spaced on a logarithmic scale between F1 and 0,4 FH. ... The sensitivity coefficient and the linearity error must be determined by measuring the output signal of the data channel against a known input signal for various values of this signal.
