Dawn at Ceres - VIR

The Dawn spacecraft is visiting the dwarf planet 1 Ceres for the time period Dec. 26, 2014 through the end of the mission (planned for summer 2016). VIR is an imaging spectrometer that combines two data channels in one instrument, Visible (VIS) and Infrared (IR). The data sets linked below will include raw (level 1a) and calibrated (level 1b) versions of all available images acquired during the Ceres Encounter.

Note: LAMO through XMO2 data are in liens resolution. Please consult the liens spreadsheet (xmlx) for the outstanding issues before using these data.

Note: As required by the peer review liens, the VIR ground correction factors, which may be applied to each band of the Ceres or Vesta L1b VIR cubes to correct for a positive slope when compared to groundbased spectra of the same target, will be included in the data volumes. Until they can be added to the volumes, they are available for download in the zip file VIR_CORRECTION_FACTORS-170907.zip
