MESSENGER MDIS CALIBRATED DATA RECORD V1.0

Published by National Aeronautics and Space Administration | National Aeronautics and Space Administration | Metadata Last Checked: August 04, 2025 | Last Modified: 2025-07-17
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 Calibrated Data Record (CDR) version of valid images than can be turned into physical units, that were acquired during the cruise phase to Mercury, and includes post- launch checkout images, flyby images of Earth, Venus, Mercury, images acquired from Mercury orbit, and inflight calibration images. This CDR dataset is the product of conversion of raw data (Experiment Data Records, or EDRs) to one of three options: physical units of radiance; or radiance factor or I/F, with or without an empirical correction for time variable instrument responsivity. In addition to the imagery, anciliary information (including calibration files used to calibrate the data) is included.
