For example , the apparent magnitude of our sun is - 26 . 8 , but its absolute magnitude is just 4 . 8 . the absolute magnitude describes the 例如太阳的视星等为- 26 . 9等，但它的绝对星等只有4 . 8等。
Game , the player needs to control small raccoons jump , the air made ornaments , color satellite , etc . , they can be passed 游戏中，玩家需要控制小浣熊跳跃，取得空中的彩球彩星等，得到它们就可以加分。
We know the luminosity is directly related to the absolute magnitude . so , in practice , we usually use absolute magnitudes instead 由于光度和绝对星等有直接的对应关系，所以很多时赫罗图会选用绝对星等。
Astronomers rate the brightness of stars by a system of numbers called magnitudes . the fainter the stars , the greater the number they are 在天文学上，星星的光度是以星等来区分的，星星越暗，等数越大。
Reference stars : star with known position and / or magnitude , that are used to find the plate constants and photometric calibration of an image 参考星：已知位置和/或星等的恒星，用于确定图片的底片常数和光度校准。
Jupiter is the second brightest planet after venus . the visual magnitude of jupiter is around - 2 . 5 a few weeks before and after the opposition 木星是除金星外最光亮的行星，木星冲前后几星期，其视星等约为- 2
To avoid this problem , you can set the upper magnitude limit to approximate the magnitude where the stars in the ccd frame are saturated 为了避免这个问题出现，你可以设置这个最亮星等极限值为本图片的接近亮度饱和的星体的亮度。
The hertzsprung - russell diagram serves this purpose . it is a plot of absolute magnitude against surface temperature i . e . , spectral type of stars 简单来说，赫罗图把大量恒星的绝对星等和表面温度或谱型关系以图表方式显示出来。
This is the apparent magnitude of an object at some standard distance from us . this standard distance is chosen to be about 32 light years 10 parsecs , see below 绝对星等是恒星距离为约32光年或10秒差距请参阅下一节时的星等。
Estimates the magnitude sensitivity , magnitude valid range and probability of star capture based on signal detection and probability statistics 以信号探测和概率统计为理论基础，对星等探测灵敏度、星等有效范围和星探测概率进行了分析与估算。
