Preferred Label : field level;
IUPAC definition : Logarithm of the ratio of two values of a field quantity, usually amplitude. Levels
are expressed in different ways: LF ln(F/F0).Np, where N p is the symbol for the
unit neper coherent with the SI, or LF 20.log10(F/F0).dB, where dB is the symbol
for the unit decibel.;
