===== TRIPLESPEC =====

Triplespec is a near-IR spectrograph, constructed at the University of Virginia. Other versions of the instrument have been used at the Palomar 200-inch and the SOAR telescope.

Triplespec provides spectra in 5 orders, with a slit-length of 43 arcsec

* IDL-based alternatives

  * [[https://legacy.apo.nmsu.edu/arc35m/Instruments/TRIPLESPEC/TspecTool/index.html|Tspectool]] is an IDL data reduction tool based on SpexTool. See 
    * Cushing, Vacca & Rayner 'Spextool: A Spectral Extraction Package for SpeX, a 0.8-5.5 Micron Cross-Dispersed Spectrograph' 
    * Vacca, Cushing & Rayner 'A Method of Correcting Near-Infrared Spectra for Telluric Absorption' 

* IRAF-based alternatives

* Python-based alternatives
  * [[https://pyvista.readthedocs.io|pyvista]] : a general basic, pedagogical, reduction package that has configuration files for TSPEC and a notebook demonstrating basic reduction
  * [[https://PypeIt.readthedocs.io|PypeIt]] : a general package for optimal extraction of spectrograph data, including echelle data. Work is in progress on a configuration for TSPEC.
