11. The out-of-plane resistivity is a factor of several hundred larger than that in-plane at all fields used in our experiments, so we believe that a quasi-2D approximation is valid throughout.

22. The phenomenological order parameter defined as in the lower inset to Fig. 3 gives, at fixed field and angle, useful information on the temperature dependence of the formation of the nematic state. It should not, however, be overinterpreted. As a macroscopic parameter, it suffers from the same flaws as the magnetization in a ferromagnet; in addition, we cannot rule out the possibility of multiband effects in which electrons in bands based on only one species of underlying orbitals participate in the nematic ordering.

38. Nematic behavior could also result from a wide variety of spin and charge textures that have not so far, been examined theoretically in the context of itinerant metamagnetism.
