Band structure of CePt2In7 measured along three typical momentum cuts. The photon electric field direction is along  – diagonal direction, i.e., 45 degree rotated with respect to the case in Fig. 6. (a1)–(a3) Band structure measured along a momentum cut around  point. The location of the momentum cut is shown by the pink arrowed line in the inset of (a1). The pink dashed line in Fig. 7(a2) marks a possible extra band between the M1 and M2 bands. (b1)–(b3) Band structure measured along  – direction. The location of the momentum cut is shown by the pink arrowed line in the inset of (b1). (c1)–(c3) Band structure measured along a cut crossing  point. The location of the momentum cut is shown by the pink arrowed line in the inset of (c1). (a1), (b1), and (c1) are original data. (a2), (b2), and (c2) are second derivative images of the original data with respect to energy. (a3), (b3), and (c3) are second derivative images of the original data with respect to momentum.
