Notes. We include only the values from literature for which we calculate P/σP > 3.0 with Tmid in observer frame. (*) From the spectropolarimetric measurements in (Barth et al. 2003), since we do not consider chromaticity in the polarisation, we show the median value of the measured polarisation on the different wavelength bins, for the three epochs they presents. (**) For GRB 030329 we made use of the data presented in Covino & Gotz (2016) and, specifically, the results presented in this review taken from Greiner et al. (2003) and Magalhaes et al. (2003). References for values from literature are: [1] (Covino et al. 1999), [2] (Wijers et al. 1999), [3] (Rol et al. 2000), [4] (Masetti et al. 2003), [5] (Bersier et al. 2003), [6] (Covino et al. 2003), [7] (Barth et al. 2003), [8] (Gorosabel et al. 2004), [9] (Rol et al. 2003), [10] (Covino & Gotz 2016), [11] (Gorosabel et al. 2010), [12] (Brivio et al. 2022), [13] (Steele et al. 2009), [14] (Uehara et al. 2012), [15] (Wiersema et al. 2012), [16] (Mundell et al. 2013), [17] (Wiersema et al. 2014), [18] (Urata et al. 2023), [19] (Mandarakas et al. 2023)
