Multiplication factors in FFTKet and FFTOperator

Hi 👋
Probably this is a stupid question: why do you need the following multiplicative factors when you perform the FFT transformations? Do you maybe have a reference for the formulas you use?
mul_before = exp.(1im*basis_l.xmin*(samplepoints(basis_r) .- basis_r.pmin))
mul_after = exp.(1im*basis_r.pmin*samplepoints(basis_l))/sqrt(basis_r.N)
(they are defined here)

It was indeed a stupid question, I've figured it out. It was straightforward.
