12/11//07 observation of star Arcturus showing visible and infrared measurements by VIR. The strong dip in the visible spectrum at 676.7 nm is not a feature of the star's spectrum, but rather from a filter in the VIR instrument. These spectra have not been calibrated, but are provided here for public interest Credit: NASA/JPL/INAF/ASI
