What software did you use and what is the output file named?

These are probably (occupied) band energies at the corresponding k point, but that's just a generic guess.

Looks like QE output, so these are the KS eigenvalues ordered in terms of band index at each k-point that is included in your k-grid.

I.e. you have computed for nbnd = 46 (either by specifying this, or by QE default). So you get 46 eigenvalues at each k-point which are the energies corresponding to that KS orbital.

To give you a concrete example, if in your system you have 32 occupied states, then at the gamma point, your highest occupied KS orbital would have an energy of 2.6863 eV. At the k-point (0, .4181, 0) it would be 2.5657, etc.

Hope this helps.
