Band structure of CePt2In7 measured along two high-symmetry momentum cuts. The electric field direction of the incident light is vertical, i.e, along direction. (a1)–(a3) Measured band structure along the direction. The location of the momentum cut is shown by the pink arrowed line in the inset of (a1). (b1)–(b3) Measured band structure along direction. The location of the momentum cut is shown by the pink arrowed line in the inset of (b1). (a1) and (b1) are original data. (a2) and (b2) are second-derivative images of the original data with respect to energy. (a3) and (b3) are second derivative images of the original data with respect to momentum.
