The quality of astrochemical models is highly dependent on reliable bindingenergy (BE) values that consider the morphological and energetic variety ofbinding sites on the surface of ice-grain mantles. Here, we present the BindingEnergy Evaluation Platform (BEEP) and database that, using quantum chemicalmethods, produces full BE distributions of molecules bound to an amorphoussolid water (ASW) surface model. BEEP is highly automatized and allows tosample binding sites on set of water clusters and to compute accurate BEs.Using our protocol, we computed 21 BE distributions of interstellar moleculesand radicals on an amorphized set of 15-18 water clusters of 22 molecules each.The distributions contain between 225 and 250 unique binding sites. We apply aGaussian fit and report the mean and standard deviation for each distribution.We compare with existing experimental results and find that the low and highcoverage experimental BEs coincide well with the high BE tail and mean value ofour distributions, respectively. Previously reported single BE theoreticalvalues are broadly in line with ours, even though in some cases significantdifferences can be appreciated. We show how the use of different BE valuesimpact a typical problem in astrophysics, such as the computation of snow linesin protoplanetary discs. BEEP will be publicly released so that the databasecan be expanded to other molecules or ice-models in a community effort.
