Notes. The columns show the name of the model set (Set), the metallicity [Fe/H] and star formation rates (SFR) adopted in the runs, the total number of simulated systems in each set (Runs), the total number of sdBs produced (sdBs) and the number of sdBs that are observable as composite sdB binaries (Obs). All sets of runs were performed with MESA code, with the exception of Set 5, which was performed with BSE code. For the models calculated with the BSE code, it is not possible to determine if they are observable.
