We thank J. X. Prochaska for comments on the paper. Parts of this research were supported by the Australian Research Council Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) through project number CE170100013. R.R.V. and K.S. acknowledge funding support from National Science Foundation Award Number 1816462. Some of the data presented herein were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among the California Institute of Technology, the University of California and NASA (the National Aeronautics and Space Administration). The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. Observations were supported by the joint Swinburne–Caltech Keck programme C143 and Swinburne Keck programmes W185 and W143. We wish to recognize and acknowledge the cultural role and reverence that the summit of Maunakea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain. This research is based on observations made with the NASA/ESA Hubble Space Telescope obtained from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract number NAS 5-26555. These observations are associated with programme id GO-16749. This research made use of Montage. It is funded by the National Science Foundation under grant number ACI-1440620, and was previously funded by the NASA’s Earth Science Technology Office, Computation Technologies Project, under Cooperative Agreement Number NCC5-626 between NASA and the California Institute of Technology.

Contributions

N.M.N. and D.B.F. organized and wrote the main body of the paper. N.M.N. and G.G.K. led the observing proposal, observations and planning of the galaxy KCWI observations, and D.B.F. provided the target selection. D.B.F. led the CGM KCWI observing proposal and N.M.N., G.G.K. and D.C.M. contributed to the proposal development and writing. N.M.N. and D.B.F. led the HST observing proposal and planning. N.M.N., D.B.F., G.G.K., D.C.M., B.R.C., K.M.S. and R.J.R.V. participated in the CGM KCWI observations and planning. D.C.M. built KCWI, developed the reduction pipeline and provided technical expertise for the observations. N.M.N. developed the KCWI gradient removal tools and performed the KCWI data reduction, SB measurements, SB profile fitting and mass calculations. D.B.F. led the analysis and interpretation of the ionization conditions. G.G.K. and J.C. assisted in the interpretation of the results. B.R.C. developed code to perform the dust extinction corrections to the galaxy disk. All authors provided feedback on the paper.
