Hello signal processing stack exchange,

I have a complex frequency-domain signal representing the impulse response of a physical system over some range of frequency space. As an artifact of the simulation, some of the points are clearly off from what would otherwise be a smooth and Kramers-Kronig-obeying curve. Any recommendations on how to interpolate this curve while entirely ignoring these outliers?
