Description
MAVKA program was developed on the base of “Observational Obscurer” (Andronov, 2001) that was rewritten in the Delphi 7 environment. It contains a set of subroutines suitable for fast viewing, interactive filtering, and processing time series, determination extremum for subintervals. The program allows to view the data and move to different parts of it, to make scale transformations, to marked subintervals for later approximation and determination extrema.
We also focused on approximations, when time series are close to the extremum of brightness of the object. So this program allows you to get precise approximation of data near the extremum but not the whole light curve.
First of all, it has been developed for variable star observers, but it can be used for any data, not only light curves.
MAVKA
Multi-Analysis of Variability by Kateryna Andrych
Software for time series analysis that allows you to determine the characteristics of extrema in a statistically optimal way.
