We note that since the VTAnDeM database is composed of alterable files, a user can manually enter (or change) quantities in the recorded data. This method allows flexibility for users in cases where corrections/modifications are necessary. For example, it is well-known that GGA functionals in DFT tend to underestimate band gaps, which affects the defect energies. To mitigate this problem, corrections to the band edge positions from, e.g., hybrid functionals or GW quasiparticle energy calculations can be specified in the Defects_Tracker.json file by modifying the "VBM" and "BandGap" tags, which rigidly shifts the band edge positions and E F range (see Section 3.2). Additionally, since GGA functionals often underestimate formation energies of compounds, elemental reference energies can be fitted to empirically reproduce experimental formation enthalpies of compounds, which often results in more accurate descriptions of experimentally-observable quantities such as carrier concentrations. The elemental energies can be modified by changing the "mu0" field in the Compounds_Tracker.json file.
