| Data Set Abstract |
A global map of a unitless
compositional parameter, delta-C_perpendicular (DCP), and propagated
1-sigma uncertainties is provided. DCP varies linearly with the
macroscopic thermal neutron absorption cross section of Vesta's
regolith. An equation for converting tabulated DCP values to
absorption units is provided in this document. DCP was determined from
thermal and epithermal neutron counting rates measured by the NASA
Dawn mission's Gamma Ray and Neutron Detector (GRaND) while in low
altitude mapping orbit, about 210 km from Vesta's surface. The
measurements are representative of Vesta's bulk regolith composition
to depths of a few decimeters with a spatial resolution of about
300-km full-width-at-half-maximum of arc length on the surface. The
methods used to determine neutron absorption are described by
PRETTYMANETAL2013. |
