Table 2 Relative and corresponding effective partial amplitudes (between parentheses). The relative amplitudes reveal which percentage of the mixture partial should be assigned to each source, hence the sum in each column is always 1 (100%). The effective amplitudes are obtained by multiplying the relative amplitudes by the mixture partial amplitudes shown in the last row of Table 1, hence the sum of each column in this case is equal to the amplitudes shown in the last row of Table 1.
