Relative abundances of several COMs with respect to CH3OH towards the components A and B of the protostellar binary IRAS 16293 (red and yellow, respectively) compared to the mean values found at the final time of our simulations (set of initial abundances A in dark blue and set of initial abundances B in cyan). The abundance ratios of IRAS 16293 come from Coutens et al. (2016), Lykke et al. (2017), Persson et al. (2018), Jørgensen et al. (2018), and Manigand et al. (2020b). The error bars correspond to an uncertainty of 30 and 10% for the components A and B, respectively. For the simulations, the bars cover the range between the minimum and maximum abundance ratios.
