I'm trying to compare:

http://docs.scipy.org/doc/scipy/reference/generated/scipy.special.pro_ang1.html#scipy.special.pro_ang1

which lists 4 parameters:

(m, n, c, x)

with this reference:

which refers to 4 parameters (see section 2):

The continuous time parameter t, the order,n, of the function, the interval

on which the function is known, t0, and the bandwidth parameter c. The

bandwidth parameter is given by c= t0?, (3) where? is the finite bandwidth

or cutoff frequency of?n(t) of a given ordern.

Unfortunately the scipy doc doesn't give a description of it's parameters or

any reference.
