Extinction curve derived in this work compared with previous results from the literature. Left: Chiar & Tielens (2006), Nishiyama et al. (2009), and Fritz et al. (2011). Centre: Schödel et al. (2010) and Hosek et al. (2019). Right: Alonso-García et al. (2017), Nogueras-Lara et al. (2018), and Nogueras-Lara et al. (2020). In all cases we translated the extinction curves from the literature to our reference filter system. For the centre and right panels, the J-band extinction value and its uncertainty were obtained by interpolating our extinction curve. Uncertainties are not available for Chiar & Tielens (2006) and are therefore not shown.
