Query: Electronic band structure of ferro-pnictide superconductors from ARPES
  experiment   ARPES experiments on iron based superconductors show that the differences
between the measured and calculated electronic band structures look
insignificant but can be crucial for understanding of the mechanism of high
temperature superconductivity. Here we focus on those differences for 111 and
122 compounds and discuss the observed correlation of the experimental band
structure with the superconductivity.
