Poisson Integral
A.k.a. Bessel's Second Integral.
where
is a Bessel Function of the First Kind and 
is a Gamma Function. It can be derivedfrom Sonine's Integral. With 
, the integral becomes Parseval's Integral.See also Bessel Function of the First Kind, Parseval's Integral, Sonine's Integral- Plane Division
