Dawn VIR Mirror C-Kernel: EXTENDED GRAND (CXG)

Description This dataset contains the binary SPICE C-kernels (.bc) representing the scanning mirror orientation of the VIR Spectrometer during the CXG of the NASA Dawn Mission at Ceres. These kernels are essential for the geometric registration and hyper-spectral data cubes projection on the planetary surface. These products are functionally identical to the official mission kernels hosted at the NASA NAIF/PDS Archive . This dataset was generated using the TM2ck Pipeline (Version 1.1), an automated tool that reconstructs mirror positions from raw Housekeeping telemetry (APID 102). https://doi.org/10.5281/zenodo.19203210数据集描述 本数据集包含二进制SPICE C内核（.bc），用于表征NASA黎明号任务在谷神星开展CXG任务期间，VIR光谱仪（VIR Spectrometer）的扫描镜姿态。 此类内核是实现行星表面几何配准与高光谱数据立方体投影的必备支撑。 本数据集生成的产品与托管于NASA NAIF/PDS档案库的官方任务内核功能完全一致。 本数据集通过TM2ck流水线（版本1.1）生成，该自动化工具可从原始管家遥测（Housekeeping telemetry，APID 102）中重构扫描镜位置信息。 数据集关联DOI：https://doi.org/10.5281/zenodo.19203210
