Abstract
A brief review of possible mechanisms for ionizing cooling flow filaments is given. Emission line ratios from spatially resolved spectra of NGC 1275, covering [OII]λ3727, Hβ, [OIII] λ5007 and [SII]λλ6717, 6730 are presented. The line ratios are shown to be incompatible with the simplest model in which the gas is photoionized by a central active nucleus and lies at its projected distance from the nucleus.
