Data Set Abstract Abstract ======== This data set consists of the MESSENGER MASCS VIRS calibrated observations, also known as CDRs. The MASCS VIRS experiment is a fixed concave grating spectrograph with a beam splitter that simultaneously disperses the spectrum onto two photodiode arrays. There are two VIRS CDR data products, one for each array, which result in coverage of the wavelength ranges of the visible (VIS) and near infrared (NIR).
