Does anyone have the mathematical definition of the flattop window, sometimes called the Potter 201 window?

(t)=0.2395-0.4581*cos(2**t/T)+0.2585*cos(4**t/T)-0.0439*cos(6**t/T) if 0<t<T otherwise (t)=0

RE: Flattop window
For the P201 window I have:
a0=0.999028
a1=2*0.925752
a2=2*0.351960
a3=0
a4=0
w = a0 - a1*cos(2*pi*t/T) + a2*cos(4*pi*t/T) - a3*cos(6*pi*t/T) + a4*cos(8*pi*t/T)
I hope this helps, Troy
RE: Flattop window
w = w / (a0+a1+a2+a3+a4)
