我们给出了木星特洛伊木马的光曲线测量结果，旨在描述木马在大约60-150公里的大小范围内的自转特性。这项调查的目的是对自转周期和幅度提供可靠和公正的估计，总共产生了80个天体的光曲线，其中56个是迄今为止公布的第一次测定，其中9个取代了之前公布的错误值。在选定的大小范围内，我们的结果是现有木马旋转属性数据库的两倍多。对自转周期和光曲线振幅分布的分析是配对论文的主题。
We present the results of a Jupiter Trojans’ light curve survey aimed at characterizing the rotational properties of Trojans in the approximate size range 60–150 km. The survey, which was designed to provide reliable and unbiased estimates of rotation periods and amplitudes, resulted in light curves for a total of 80 objects, 56 of which represent the first determinations published to date and nine of which supersede previously published erroneous values. Our results more than double the size of the existing database of rotational properties of Jovian Trojans in the selected size range. The analysis of the distributions of the rotation periods and light curve amplitudes is the subject of companion papers.
