Measured band structure of CePt₂In₇ along high-symmetry directions ––– of the BZ and the comparison with calculated results. (a) Original data consisting measurements along three momentum cuts. The location of the momentum cuts are indicated by pink lines in the inset. (b) Second derivative image of (a) with respect to energy. (c) Second derivative image of (a) with respect to momentum. The dashed white lines in (b) and (c) represent calculated energy bands at .
