Spextool (Spectral EXtraction TOOL) is an IDL-based data reduction package for SpeX, a medium resolution near-infrared spectrograph on the NASA IRTF.  It performs all of the steps necessary to produce spectra ready for analysis and publication including non-linearity corrections, flat fielding, wavelength calibration, telluric correction, flux calibration, and order merging.  Spextool was written by Michael Cushing, Bill Vacca, and John Rayner.  I have also modified Spextool to reduce data obtained with TripleSpec on the Palomar 200″, TripleSpec on the 3.5m APO, and the low-resolution single order mode on FIRE on the 6.5m Magellan (See below for more information on these modes.)

The current stable version of Spextool (v3.4) can be downloaded from the Spex website.
