An asymmetrical Apodization Function defined by

0 & for $x<-b$\cr
(x-b)/(2b) & for $-b<x<b$\cr
1 & for $b<x<b+2d$\cr
0 & for $x<b+2d$,}

where the two-sided portion is $2b$ long (total) and the one-sided portion is $b+2d$ long (Schnopper and Thompson 1974, p. 508). The Apparatus Function is

M_A(k,b,d)={\sin[2\pi k(b+2d)\over 2\pi k}+i\left\{{{\cos[2\pi k(b+2d)]\over 2\pi k}-{\sin(2b)\over 4\pi^2 k^2 b}}\right\}.
