Popis:	We report a study of the magnetoresistivity of high purity Sr${}_{3}$Ru${}_{2}$O${}_{7}$, in the vicinity of its electronic nematic phase. By employing a triple-axis (9/1/1 T) vector magnet, we were able to precisely tune both the magnitude and direction of the in-plane component of the magnetic field (${H}_{\ensuremath{\parallel}}$). We report the dependence of the resistively determined anisotropy on ${H}_{\ensuremath{\parallel}}$ in the phase, as well as across the wider temperature-field region. Our measurements reveal a high-temperature anisotropy which mimics the behavior of fluctuations from the underlying quantum critical point, and suggest the existence of a more complicated phase diagram.
