An apodization function given by
 | (1) |
which has full width at half maximum of 
. This function is defined so that the coefficients are approximations in the general expansion
 | (2) |
to
which produce zeros of 
at 
and 
.
The corresponding instrument function is
 | (6) |
where 
is the sinc function. It is full width at half maximum is
