Galaxy-only B/T ratio versus galaxy minus PS B/T ratio for 187 GOODS X-ray AGN colored by the ratio of light in the PS to the host galaxy (PS ratio). Note that the majority of fits with PS ratio > 1 show large diversions between the fit results. In some of these cases, the two-component only fit performs comparably to those with a PS subtracted, but for many sources with a large PS contribution, the B/T ratio appears to be overestimated if a PS is not subtracted. Sources above the +1σ line show, except for three galaxies, no improvement and even some evidence for overfitting if a PS is included.
