Is not Parameter P the hard and soft iron component of magnetism acting in the fore and aft fuselage axis and composed of Coefficient B.
Parameter Q is the same in the athwartships axis and is composed of Coefficient C.
Parameter R is the one in the vertical axis and give rise to Coefficient D.
???????
The Coefficient A is the residual magnetism?
It has been a long time but I think Kermode has a word or two to say on the subject. So the answer to your question would be B?
