Description of the Ceres Urvara Dawn FC C2E mosaic bundle V1.0 ============================================================== Bundle Generation Date: 2025-03-20 Peer Review: 2024_Asteroid_Review Discipline node: Small Bodies Node Content description for the Ceres Urvara Dawn FC C2E mosaic bundle ================================================================== Bundle Description ================== This bundle contains controlled mosaics of the Urvara crater region using Dawn FC2 level 1b calibrated images from the Ceres X2 Elliptical (C2E) mission phase. Approximately 1600 images are used, with resolutions varying from a few m/pixel to around 40 m/pixel. Images are controlled relative to each other and to the Dawn LAMO basemap, and are photometrically corrected to account for varying illumination conditions. A single large mosaic is included, with all images scaled to 5 m/pixel resolution, along with four subset mosaics incorporating only those images in different ranges of native resolution: 3.5-7 m/pixel, 7-14 m/pixel, 14-28 m/pixel, and greater than 28 m/pixel. When layered together, the four submosaics include all images contained in the full mosaic. Documents --------- productdescription.txt This document details the processing steps used to create the mosaics, including image selection, image control and registration, photometric correction, and final mosaic assembly. urvaramos.txt List of all images used to generate the main mosaic, using the original PDS filenames. The first images listed are the lowest layer of the mosaic, and subsequent images are overlaid on top of them. urvaramos_3_5to7mpp.txt List of all images used to generate a subset mosaic using just the images with a native resolution between 3.5 and 7 m/pixel. The original PDS filenames are used. The first images listed are the lowest layer of the mosaic, and subsequent images are overlaid on top of them. urvaramos_7to14mpp.txt List of all images used to generate a subset mosaic using just the images with a native resolution between 7 and 14 m/pixel. The original PDS filenames are used. The first images listed are the lowest layer of the mosaic, and subsequent images are overlaid on top of them. urvaramos_14to28mpp.txt List of all images used to generate a subset mosaic using just the images with a native resolution between 14 and 28 m/pixel. The original PDS filenames are used. The first images listed are the lowest layer of the mosaic, and subsequent images are overlaid on top of them. urvaramos_gt28mpp.txt List of all images used to generate a subset mosaic using just the images with a native resolution greater than 28 m/pixel. The original PDS filenames are used.
