标题： Correction of the VIR-visible data set from the Dawn mission at Vesta

摘要： 这项工作描述了应用于由可见光通道获取的小行星(4)灶神星数据集的校正方法。 在可见波长的数据采集过程中，探测器温度上升导致整个光谱范围内的光谱斜率增加。 这限制了在此波长范围内对灶神星表面研究的准确性。 在此，我们详细说明了一种经验性方法，用于校正可见探测器温度依赖性，同时考虑灶神 dataset 的特殊性。 显示英文摘要

摘要： This work describes the correction method applied to the dataset acquired at the asteroid (4) Vesta by the visible channel of the visible and infrared mapping spectrometer. The rising detector temperature during data acquisitions in the visible wavelengths leads to a spectral slope increase over the whole spectral range. This limits the accuracy of the studies of the Vesta surface in this wavelength range. Here, we detail an empirical method to correct for the visible detector temperature dependency while taking into account the specificity of the Vesta dataset.
