Fig. 9.
Redshift distributions of the SPICY PAH galaxies (left) and the optical spectroscopic sample of Shim et al. (2013) towards the NEP (right). In the right panel, we only show the sources with good redshift measurements (quality flag of 3 or 4 in Shim et al. 2013; see text). We also indicate ranges of the three redshift bins; nearby (including 13 PAH galaxies), mid-z (23), and higher-z (12) bins, in the left panel.
