We present the final results from our deep HST imaging study of the host galaxies of radio-quiet quasars (RQQs), radio-loud quasars (RLQs) and radio galaxies (RGs). We describe and analyze new WFPC2 R-band observations for 14 objects which, when combined with the first tranche of HST imaging reported in McLure et al (1999), provide a complete and consistent set of deep, red, line-free images for statistically-matched samples of 13 RQQs, 10 RLQs and 10 RGs in the redshift band 0.1 10% at z~=2 − 3 (Refer to PDF file for exact formulas).. Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by The Association of Universities for Research in Astronomy, Inc. under NASA contract No. NAS526555.
