IRTF/SpeX spectra (black) compared to spectral standards (red).

IRTF offers the possibility of remote data reduction, e.g., for those observers without an IDL license at their home institution. IRTF's standalone workstation Freia is set up for this, and can be accessed via VNC. Freia comes with IDL, and Spextool for SpeX and iSHELL installed.
