Visible and Infrared Spectrometer Data
 |
|
| The Visible and Infrared (VIR) Mapping Spectrometer "sees" from 0.3-5 microns covering the near ultraviolet (UV), visible and infrared regions of the spectrum. The instrument produces an image of the spectrum which is colored according to a specified color palette (top) and is shown as a line plot or row profile (bottom). The spectrometer has on board its own calibration lamp, which it imaged as part of the tests performed in the weeks after launch. + Enlarge image |
