You can access the Fermi surface associated to a given dataset with
.S.fermi_surface, which will give the Fermi surface integrated in a
reasonable range (30 millivolts) of the chemical potential.
You can use this to rapidly plot Fermi surfaces
Alternatively, you can use
arpes.plotting.dispersion.labeled_fermi_surface to get a Fermi
surface that optionally includes the labeled high symmetry points.
You can also add annotations manually.
