论文摘要
小行星的时间分辨光度法可用于形状和自旋重建。如果每个小行星的测量次数不足以创建模型，则可以使用整个数据集重建人群中形状伸长和极纬度的分布。这是通过重建从（假定）恒定角度观察到的点的分散点来估计的灯曲面的幅度来完成的。在这里，我们制定了轨道平均的方法，其中可观察到的是亮度的轨道平均分散体。
Time-resolved photometry of asteroids can be used for shape and spin reconstruction. If the number of measurements per asteroid is not sufficient to create a model, the whole data set can be used to reconstruct the distribution of shape elongations and pole latitudes in the population. This is done by reconstructing amplitudes of lightcurves that are estimated from dispersion of points observed at (assumed) constant aspect angle. Here, we formulate orbit-averaged approach where the observable is the orbit-averaged dispersion of brightness.
