[Wien] How to reduce the number of energy bands being calculated

Dear Wien community, I want to render the Fermi surface of a system with a few hundreds of atoms. Are there any ways to force the calculation just to find the bands near the Fermi level? I have done some tests using Copper. I increased Emin in case.in1 from default (-9.0) to -2.0, there was an er
