摘要

我们开发了软件包MAVKA，用于确定极值(极值矩、幅值)及其误差的特征。该程序实现了11个基本函数在极值逼近中的应用。我们分两部分测试了所有这些方法。在第一部分中，我们使用生成的数据集(各种带噪声的平滑曲线)。我们研究了极值和幅度矩的生成值与计算值之间的偏差，以及不同极值参数的执行时间。在第二部分中，我们使用了来自不同数据库的光度和视觉观测数据对不同变星进行了实际观测。

MAVKA: Investigation of stellar brightness extrema approximation stability for various methods

We developed the software package MAVKA for the determination of characteristics of extrema (moment of extremum, magnitude) and their errors. The program realizes the application of 11 basic functions for approximation of extrema. We tested all these methods in two parts. In the first part we used generated data sets (various smooth curves with noise). We investigated deviations between generated and computed values of moments of extremum and magnitude, as well as execution time for different extrema parameters. In the second part we used real observations of different variable stars using photometric and visual observations from different databases.
