Presented are calculations of the photon-limited radial velocity sensitivity of the TripleSpec Externally Dispersed Interferometer for a series of M-type stellar models. This instrument uses an interferometer before the dispersing element of a moderate-resolution spectrograph to boost radial velocity precision and reject systematic noise.
