The best way to learn how to use Period04 is by doing. For this reason we created a few example time strings which will be processed and discussed in the tutorials below. The data files can be downloaded from the Period04 homepage:

Tutorial 1:


In this tutorial we will use Perio04 to examine a data set and determine the frequencies by using Fourier analyses to give us rough values of the frequencies and the fit module to refine these frequencies.

Tutorial 2:
Least-squares fitting of data including a periodic time shift


The second tutorial provides a basic introduction in how to find a multiple frequency solution to a data set taking into account a periodic time shift.

Tutorial 3:
Exchanging data with Virtual Observatory (VO) applications


Learn how to use the interoperability tools implemented in Period04
