[RING PSEUDO-IMAGE]

Overview

The Cassini Ultraviolet Imaging Spectrograph (UVIS) has two spectrographic channels that provide images and spectra covering the ranges from 56 to 118 nm and 110 to 190 nm. A third optical path with a solar blind CsI photocathode is used for a high signal-to- noise ratio, stellar occultation by rings and atmospheres. A separate hydrogen deuterium absorption cell measures the relative abundance of deuterium and hydrogen from their lyman-alpha emission.

UVIS Occultation Profiles Updated May 2014

    The PDS Rings node has a dataset of Saturn ring radial profiles derived from UVIS stellar occultation data. The data include ring radial profiles at 1 and 10 km resolution from more than 50 UVIS stellar occultations. The dataset has completed peer review and is now in lien resolution. Although there are a few liens against the data set it has been PDS certified and is eligible for use under some ROSES 2014 programs.

    A few liens are specific to the data as opposed to the documentation. These are described in the ERRATA.TXT file located in the root directory of the data set.

    Users may browse the data set COUVIS_8001, or download the entire data set COUVIS_8001 tar.gz.
