Presented are calculations of the photon-limited Doppler sensitivity
of the TripleSpec Externally Dispersed Interferometer (TEDI)
near-infrared instrument designed for the Palomar 200" Hale Telescope
for a series of low-mass stellar models.  Also, the effects of
telluric model uncertainty are considered for a particular stellar
model.  This spectrograph uses an interferometer before the dispersing
element to boost resolution and reject systematic noise.  Explanations
of the calculations, including interpereting the EDI signal, are given
along with the results.
