MESSENGER MDIS MAP PROJECTED BASEMAP RDR V1.0
Abstract ======== The Mercury Dual Imaging System (MDIS) consists of two cameras, a Wide Angle Camera (WAC) and a Narrow Angle Camera (NAC), mounted on a common pivot platform. This dataset includes the Basemap Reduced Data Records. The Map Projected Basemap RDR (BDR) data set consists of a global map of I/F measured by the NAC or in WAC filter 7 (both centered near 750 nm) at moderate/high incidence angle, photometrically normalized to a solar incidence angle (i) = 30 degrees, emission angle (e) = 0 degrees, and phase angle (g) = 30 degrees at a spatial sampling of 256 pixels per degree. The map is divided into 54 segments or 'tiles', each representing the NW, NE, SW, or SE quadrant of one of the 13 non-polar or one of the 2 polar quadrangles or 'Mercury charts' already defined by the USGS. Each tile also contains 5 backplanes: observation id for each included image; BDR metric, used to determine the stacking order of component images; solar incidence angle; emission angle; and phase angle.
