Violin plots of different properties of global/integrated GRB host spectra (blue plots) and the same properties at the resolved GRB sites (green plots). The dots are the global values for the host of GRB 171205A, diamonds are the values at the GRB site of GRB 171205A. Emission lines for the integrated host spectra were obtained from the samples of Krühler et al. (2015), Han et al. (2010), with additional single GRBs from Della Valle et al. (2006), Christensen et al. (2008), Kelly et al. (2013), Schulze et al. (2014), Thöne et al. (2014), Izzo et al. (2017), Heintz et al. (2018), Cano et al. (2017b), de Ugarte Postigo et al. (2018, 2020), Melandri et al. (2019). Stellar masses were taken from the GHostS database (http://www.grbhosts.org) and Palmerio et al. (2019). Rest-frame B-band magnitudes to derive the sSFR were taken from the TOUGH sample (Hjorth et al. 2012) and Krühler et al. (2011). Hα EW were determined from public spectra stored in the GRBspec database (de Ugarte Postigo et al. 2014b). The values for the GRB sites were taken from Christensen et al. (2008), Thöne et al. (2014), Izzo et al. (2017), Cano et al. (2017b), de Ugarte Postigo et al. (2018), Melandri et al. (2019).
