MP ANION CORRECTION: According to the paper by Wang et al (1), a correction of 1.36 eV per O2 is suggested for oxides. But for MnAl2O4 in MaterialsProject, it is written  5.6183 eV (MP Anion Correction) which is approximately 4 times of 1.40 eV. So shouldn’t the Anion Correction be 2 times of 1.36 ev?
MP ADVANCED CORRECTION: According to the paper by Jain et al (2), all GGA+U calculation is adjusted by (n)*(∆E) and for MnAl2O4, n=1 (only one Mn) and ∆E=1.687. But in the calculation here in MP, a value of 3.3617 eV is given as the correction which is 2 times that of 1.687 eV. Should it be 1.687 eV instead of 3.3617 eV?
Appreciate your response! Thanks!
