Notes. (1)The SED templates are taken from Coleman et al. (1980) for the far UV and visible and extended to the near-IR. (2)The extinction curve is taken from Fitzpatrick & Massa (2007) and extended to the near-IR. (3)The extinction curve is corrected for the intergalactic medium effects as in Madau et al. (1996). (4)Stars are added following the Besançon model of Robin et al. (2003) and their recent improvements (Robin et al. 2012, 2014; Bienaymé et al. 2015; Amôres et al. 2017). (5)For a full description of these parameters, see Sect. 2.4. (6)For a full description of these parameters see Sect. 2.5.
