| dc.description.abstract (摘要) | This study examines the effects of crater-size frequency data collections and modeling parameters to better understand their influence on model ages for Cerealia Facula on Ceres. Key factors in this investigation include (a) analyst-dependent data collection, (b) slope discrepancies between measured distributions and modeled production functions, and (c) choice of chronology models. The foundational cartographic product for this work is a novel controlled high-resolution image mosaic built from data of NASA’s Dawn Framing Camera in XMO7 orbit. Our study returns crater-based absolute model ages for Cerealia Facula using the Lunar-derived chronology model (4.23 ± 0.36 Ma) and the Asteroid-flux-derived chronology model (0.43 ± 0.04 to 39.53 ± 3.26 Ma). Results show that model ages derived from small-area measurements are highly sensitive to (1) data collection bias and variability, particularly for craters smaller than 50 m, (2) the chosen distribution diameter range for age modeling, and (3) the chronology model, which can shift ages by a factor of up to 10. For complex regions like Cerealia Facula, using larger craters across wider areas offers more robust results. This investigation highlights the importance of high-resolution datasets for improving CSFD reliability and emphasizes the need for consistency in data collection and model selection. To provide additional geological context, an IHS pan-sharpened RGB orthomosaic was generated from XMO7 clear-filter data combined with LAMO-based RGB data, covering both Cerealia Facula and Vinalia Faculae at a ground sample distance of 8.5 m. The corresponding mosaics have been uploaded at the Zenodo (https://zenodo.org/records/17615401) data repository and are permanently accessible. | |
