Time Series Analysis in Astronomy (PAP312: 5pts)

Timetable in autumn 2025

Main idea of the course

The period analysis method Discrete Chi-square Method (DCM) was formulated in

to the same directory in your computer. In this course, we apply DCM to simulated data. DCM is also compared to other time series analysis methods, like the Discrete Fourier Transform (DFT).

Some DCM application examples are taken from | Jetsu (2021: The Astophysical Journal, vol 920, 2:137 | "Say Hello to Algol's New Companion Candidates" (Paper II).

Grading of course

There are no exams. The students will perform assignments. The number of assignments completed by the student determines the grade received of this course. There will be N=10-12 exercises. The evaluation criteria of each Exercise are

  • 0/2 (Exercise not done at all, or it makes no sense)
  • 1/2 (Exercise is a good try)
  • 2/2 (Exercise is correct, or nearly correct)
  • The maximum points are NMAX = 2 x N pts. The grade limits are

  • 0/5 = <45% of NMAX
  • 1/5 = 45-55% of NMAX
  • 2/5 = 55-65% of NMAX
  • 3/5 = 65-75% of NMAX
  • 4/5 = 75-85% of NMAX
  • 5/5 = <85% of NMAX
