Thanks for the reply!. What I am looking for is the solution posted by "ldvbin". That code works in MATLAB but for some reason the exact algorithm doesn't work in IDL. In either case, can some one help me with how to relay that information to a data where I have flux data values against...
I have a spectrum with flux on the Y-axis and wavelength on the X-axis. What I want to do is take the Fourier transform of this spectrum. Then add a random phase between 0 and 2pi to the phase only. Then take the inverse Fourier Transform of this. The piece of code I wrote in IDL for a simple...
I have some questions regarding shifting the phase of a Fourier transformed spectrum :
