Stellar spectra of the planet host stars. G0V-K5V hosts are comprised of IUE UV data from Rugheimer et al. (2013), and the M5V host comes from UV observations of GJ 876 from the MUSCLES survey (France et al. 2016). Visible and IR wavelengths use ATLAS models of the same stellar temperature (Kurucz 1979). The right-hand figure zooms in on the UV region relevant for photolysis with important biological UV regimes (see Sect. 4.4).
