However, the lower bound of the precession period provided may be far less than the true precession period, which will seriously degrade the estimation performance.
进动周期下限可能远小于真实进动周期，此时自相关法的估计性能将严重下降。
The difference function between the ACF and the convex hull is obtained, and then the precession period is estimated by searching for the maximum value of the difference function.
首先求出acf和其凸包的差函数，然后搜索差函数的最大值，从而得到进动周期的估计值。
Two correlations have been raised and sustained by observational values, which are precession period - absolute magnitude correlation and black hole mass - precession cone semi-angle correlation;
提出两个关系，即进动周期—绝对星等的关系和黑洞质量—进动锥角的关系；
