以下是Science result页面的翻译。
Here λ and β are ecliptic longitude and latitude of the spin axis direction and P is the rotation period. Usually, there are two possible pole directions and corresponding shape models for one asteroid - the lightcurve inversion cannot solve this ambiguity for asteroids orbiting close to the ecliptic plane. Each figure shows the corresponding shape model from its equator (the first two views, 90 degrees apart) and pole-on (the third view). The 'computed by' column lists all users that provided valid results that contained the solution listed in the table.
这里的λ&β是旋转轴的黄道经度、纬度,P是旋转周期。通常一个小行星有两种可能的极方向(译注:pole directions是极方向么?)和对应的形状模型 - lightcurve inversion(译注:lightcurve inversion查不到什么翻译)不能解决小行星轨道接近黄道平面的模糊性。每一个图片都展示了从小行星(推导出的)形状 - 头两张视角处于赤道平面并相差90°;第三张是pole-on视角(译者注:大概就是像从南极点或者北极点看地球一样)。以下“computed by”例表中展示了提供可用数据用户的名单。
介绍页面上的关于lightcurve inversion的一段解释
Because asteroids have in general irregular shapes and they rotate, the amount of sunlight they scatter towards the observer varies with time. This variation of brightness with time is called a lightcurve. The shape of a lightcurve depends on the shape of asteroid and also on the viewing and illumination geometry. If a sufficient number of lightcurves observed under various geometries is collected, a unique physical model of the asteroid can be reconstucted by the lightcurve inversion method.
因为小行星有着不规则的形状并且一直在旋转,他们对观测者散射的阳光随着时间的变化不断变动。这种随着时间流逝发生的明亮度的变动就被称为lightcurve。lightcurve的形状取决于小行星的形状,也取决于视角、照明几何(也许叫做光照情况更通俗)。如果在不同光照几何下归集足够数量的小行星形状的lightcurves,就能通过lightcurve inversion法重建并推导出小行星唯一的物理模型。
