Two significant structures can be observed: a bending structure at $\\hbar\\omega\\sim$85 meV in TaAs, and peaks at $\\hbar\\omega\\sim$ 50 meV (TaP) and $\\sim$30 meV (TaAs). The bending structure can be explained by the interband transition between saddle points connecting a set of $W_2$ Weyl points.
