Sine fitting - extra modulation - Pikano - Jan-03-2023

Hi,
I have some issues with sine fitting, I use a very simple sine equation
y = a + b*np.sin(N_p*theta+c)
but the result gives me some kind of extra modulation on amplitude. Maybe someone has experienced a similar issue?

Which code produced the chart?
