MESSENGER E/V/H MASCS 4 VIRS DERIVED DATA V2.0
type: Dataset
description: Abstract ======== This data set consists of the MESSENGER MASCS VIRS derived observations, also known as DDRs. 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 DDR data products, one for each array, which result in coverage of the wavelength ranges of the visible (VIS) and near infrared (NIR). This is version 2 of this data set; version 1 is available on PDS volume MESSMAS_2001.
