     What kind of spline is used can be provided in the ~interpolator_kind~ field.
     For example, FHI-aims uses a cubic spline, so the ~interpolator_kind~ is
-    \"polynomial\" and the ~interp_coeff_cnt~ is $4$. In this case, the first
+    \"Polynomial\" and the ~interp_coeff_cnt~ is $4$. In this case, the first
     interpolation coefficient per data point is the absolute term, the second is for
     the linear term etc.
     The interpolation coefficients for the wave function are given in the
