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= t0Ω, (3) whereΩ is the finite bandwidth
or cutoff frequency ofψn(t) of a given ordern.
Unfortunately the scipy doc doesn't give a description of it's parameters
