理论分析和实验结果表明，该方法比光度立体学、球谐函数方法具有较高的精度和较强的实用性。
Theoretical analysis and experimental results both show that our method has higher precision and better practicability compared with photometric stereo harmonic image method.
例如，如果两颗恒星的大小相同，但是在开氏温标下，一个比另一个的温度高一倍，那么前者的光度将是后者的16倍。
For instance, if two stars are the same size but one is twice as hot as the other in kelvin, the former would be 16 times as luminous as the latter.
NGC 1427a是个典型的矮星系、不规则星系，它们的外形不规则，并且光度比规则星系(涡旋星系、椭圆星系)小。
NGC 1427a is an example of a dwarf irregular galaxy, a type of galaxy that is significantly less bright than regular galaxies and characterised by a peculiar shape.
