Normalized histogram of sampled BEs (in kJ/mol) for CO, fitted with a single component gaussian profile. Previously reported results of CO BE values onto water ice analogs with diverse simulation methods are given on top. See Fig. 2 for the meaning of horizontal intervals, vertical dashed lines, and the plain gray line. Ref: [1] Ferrero et al. (2020); [2] He et al. (2016) and Penteado et al.
