Dear all,
I noticed that, as soon as I try to do a Hankel Transform (nu = 0) on a
gaussian of the form exp( - pi * r^2 ), transform it back and multiply by the
factor Jzero0(0,N)^2, that I don't get the exactly same function back.
Actually, the function that is returned is scaled by a factor 1.00391 with
respect to the original function.
For just one transform it can be considered as just a numerical error, but as
soon as I try to do some more complicated stuff I get strong abbreviations from
the real result.
I'm not sure if this is a bug, or just a misunderstanding of the concept, but
it would help me a lot if someone could give me an idea.
Regards,
Benno REM
