Contains three spectral cubes of Jupiter at 5 microns obtained on 16 January 2016 (UT) using Texas Echelon X-Echelle Spectrograph (TEXES) mounted on the InfraRed Telescope Facility (IRTF) at Mauna Kea, Hawaii. The spectral cubes have a size of ~60x95 pixels, depending of the cube. On each spectral cube, nearly all the disk of Jupiter is visible, lacking only a few pixels near the poles. The three spectral cubes together cover the 90--360 system III degree west longitudinal range. The spectral range is comprised between ~1930 and ~1945 cm-1 (~5 microns), divided in ~200 samples with a spectral resolution of ~0.15 cm-1. This spectral range contains essentially a NH3 line located at ~1939 cm-1, and probes the atmosphere of Jupiter in the 1--4 bar region. More informations can be found in the README file (including a file format description and examples of utilization), and in the related article.
