Abstract
It depends. Our experiment reveals that, given an optically thin coma, generally, the smaller the signal ratio of nucleus to coma, the less reliable is the cometary nucleus-extraction technique. We strongly suggest the technique only be applied to cases where the nucleus signal occupies 10% of the total signal wherein the bias is no more than a few percent. Otherwise there is probably no way to debias results from this technique in reality, since its reliability is highly sensitive to entangling complications, including the coma profile, and the point-spread function (PSF).
