摘要
En 中文
Frequency analysis of pulsating stars can be performed via several algorithms. Still, each of these methods has its own specific flaws which advocates for the use of as many tools as possible. However, the lack of simple programs with straightforward interface impedes such a goal. pdm13 is a new software dedicated to spectral analysis based on the phase dispersion minimization technique. Its graphical environment, combined with complementary tools, such as auto-segmentation, makes it a simple and powerful mean for frequency extraction. In this paper, a detailed description of the mathematical algorithms is presented. Then, we introduce the options and interface of pdm13. Finally, we compare the results from different case study using pdm13 and other programs.
