a, d Raw magneto-reflectance data [R(B) − R(0)]/R(0) for H⊥a and H∥a, respectively (b, e) Optical conductivity in field calculated from the zero-field reflectivity of ref. 19 and the magneto-reflectance data for both in-plane field orientations. Insets: evolution of the 29 meV peak as a function of the field for the merged datasets from HF and SC experiments. The arrows, indicating the peak position for selected fields, highlight the stronger redshift for M∥a (5,15,34 T in (b) and 1,5,10,16 T in (e)). c, f Comparison of the zero-field and high-field conductivities with ab initio calculations for both field directions.
