This document contains the dataset used in the work « A spectral study of the Caloris basin on Mercury and the origin of associated volcanic smooth plains ». In this study the authors use NASA/MESSENGER/MASCS/VIRS DDR data available at the PDS GeosciencesNode of Washington University, St. Louis, MO, USA. The dataset used contains the latest calibration provided by the MESSENGER science team. (https://ode.rsl.wustl.edu/mercury/pagehelp/Content/Missions_Instruments/MESSENGER/MASCS/VIRS/Intro.htm). The present document contains VIRS DDR reflectance spectra from PDS corrected by the methodology developed by Besse et al., 2015 (https://doi.org/10.1002/2015JE004819). Moreover, the document contains the ref_id, the latitude [deg] and longitude [deg] of every footprints used in « A spectral study of the Caloris basin on Mercury and the origin of associated volcanic smooth plains » . All spectral parameters can be calculated directly with these spectra.
