I used pymatgen to extract the data for the valence and conduction bands for material RbFe(MoO4)2 (mp-18868) and noticed a discrepancy between the pymatgen output and that on the website interactive plot.
The pymatgen output says the material is a direct band gap material, but the interactive electronic structure plot lists it as a indirect band gap semiconductor. Both also list different band gap energies.
The valence band is fairly flat, so I don’t know if it’s due to a rounding error or something along those lines. Is there any way to figure out which one is correct?
