A correlation between these two quantities would suggest that the X-rays coincident with NAT galaxies are generated by the AGN that fuel the radio source. Although a trend seems to be present, there is no statistically significant correlation. This figure is from a previously published work. The dotted line is the best-fitting HRI point response function.
Data points are the azimuthally averaged surface brightness within each annulus.
The solid line is the sum of the PRF and the beta model.
