Interpixel capacitance (IPC) is a relatively new form of pixel cross-talk that involves a capacitive coupling between pixels and may cause discrepancies in astronomical measurements if not suitably accounted for. IPC effectively spreads out the signal, changing the perceived point spread function (PSF) of the detector. This investigation has developed a model based on the James Webb Space Telescope (JWST) to look at the effect of varying degree on astronomical photometry and centrioding in both isolated stars and crowded fields. We give motivation for this research along with preliminary results.
