We describe development of the data reduction process for TEDI, the Triplespec Exoplanet Discovery Instrument. The instrument consists of a near infrared interferometric spectrometer, which is used as a precision radial velocimeter. TEDI joins Externally Dispersed Interferometery (EDI), a combination of interferometry and dispersive spectroscopy, with an efficient, medium-resolution, near infrared (0.9 - 2.4 µm) echelle spectrometer (TripleSpec). The analysis pipeline for this instrument is a complex set of procedures that involves utilizing many standard echelle spectrograph reduction techniques for image cleaning and smoothing, such as locating echelle orders and applying flat-field corrections, as well as performing Fourier transformations. Because the interferometer creates a periodic comb that multiplies against the input spectrum to create moiré fringes, time and frequency domain transformations are required to extract the new, higher resolution starlight spectrum from this combination of signals. With the reduced data, the stellar Doppler shifts can then be determined to a high degree of precision. The instrument is now operating at the Palomar observatory and the analysis pipeline is currently being optimized.
