土卫六表面的相对高度

　　这是用卡西尼号上的雷达探测出的初步测高数据制成的图表，显示出土卫六上地表的相对高度。这些资料是2004年10月26日“卡西尼”号第一次接近土卫六获得的。观测地在北纬25度，西经5度。

　　This graph, produced using preliminary altimetry data from Cassini's radar instrument, shows relative surface heights on Titan. The data were acquired on Oct. 26, 2004, during Cassini's first close encounter with Titan, at distances ranging from 5,000 to 10,000 kilometers (3,100 to 6,200 miles). The location observed is near latitude 25 degrees north, longitude 5 degrees west.
