Hessian is 2nd order differential of Gaussian

Now, what number is in Hessian Matrix.
example:
Gaussian equation = F(x,y)= (1/(2*pi*T^2))exp-((x^2+y^2)/2T^2)
Then,
H = [Fxx(x,y) Fxy(x,y) ;
Fyx(x,y) Fyy(x,y)]

So, what is significant number of matrix content?

Fx = -(1/(2*pi*T^2))x/T^2 exp(-(x^2+y^2)/2T^2)
Fy = -(1/(2*pi*T^2))y/T^2 exp(-(x^2+y^2)/2T^2)

a = Fxx = (1/(2*pi*T^2))(x^2/T^4 - 1/T^2)exp(-(x^2+y^2)/2T^2)
b = Fxy =  (1/(2*pi*T^2))(xy/T^4) exp(-(x^2+y^2)/2T^2)  
c = Fyx = Fxy 
d = Fyy = (1/(2*pi*T^2))(y^2/T^4 - 1/T^2)exp(-(x^2+y^2)/2T^2)
