Blue histograms show the energy (top) and mass (bottom) outflow rates estimated for our sources with robust NaD detections, given a flow radius of 1 kpc for all sources. The estimated jet mechanical power is represented by the aqua histogram in the top panel, which can be compared with that of radio sources with H i absorption detections (white; Morganti et al. 2005a). The jet power estimates would be about an order of magnitude greater if we used the relationship from Cavagnolo et al. (2010).
