En-passant (if my understanding is correct) is a special case when a pawn reaches the 5th rank and the opposing adjacent pawn moves two squares on its first move. The pawn on the 5th rank then has the option (only on its next move) to capture the opposing pawn as if it had moved only one square. If this is the case, then en-passant would be considered as a normal capture covered under 'Magnitude 1 - Capture Only'. In other words, the 'Movement' of the capture of a Pawn(P) done by en-passant is the same as the 'Movement' of the capture of a Pawn(P) done normally.
