This characterization is similar to but not equal to a beam pattern in the usual sense where it is assumed that the acoustic waves propagate in free field and no scattering is considered.
Thus, if x and y have values a and b on their own, and x-plus-y has value c "as a whole," the value of x-plus-y "on the whole" is a + b + c. (The value of the whole is therefore not equal to the sum of the values of its parts, but is equal to a sum of which those values are constituents).
The same was done for relationships that were qualified as related but not equal to a single target concept or targets.
Paterson tried in vain to grab an equaliser, but Reina was equal to a powerful shot on the turn and the English side side emerged with a first-leg lead to take back to Anfield.
