and 10$^{\circ}$ from the c-axis respectively. Two sets of Weyl points develop in the band structure for the canted system. The first set consists of two pair of Weyl nodes at momentum coordinates (0.193,0.193,0.12), (0.193,0.193,-0.09) and symmetry related points. In figure \[fig:cant\](a) and \[fig:cant\](b), along the $k$-space cut along the M-$\Gamma$ line, the Weyl point can be seen to be developing near 200 meV. The other four Weyl nodes are at (0.394, 0.045, 0.131) and symmetry related points. Details of these Weyl node structures have been discussed in reference [@borisenko2015time]. Note that for all points, there are certain non-idealities (both in distortions of the bands and their position from E$_F$) when compared to the simplest Weyl band structure proposed in [@PhysRevB.93.085442] which would make the observation of Weyl physics in the optical response challenging.

The inter-band conductivity for these three levels of canting, as well as the experimental data is plotted in figure \[fig:cant\](c). Note that a peak slightly above 200 cm$^{-1}$ gradually develops as one includes the effect of canting in the band structure. Nevertheless, one must be cautious in claiming this to be evidence for the WSM phase as there are noticeable alterations in the band structure unrelated
