About SMURFS

Functionality

At its heart, SMURFS is a tool designed to extract significant frequencies from a time series in a fully automated way. SMURFS can be very easy to use, and give you quick insight into the data. It is also designed to be as configurable as one wants it to be, and it is possible to drill down to the individual frequencies.

In its simplest form, one only needs to provide a name of a star that is observed by the missions supported by SMURFS (e.g. TESS, Kepler, K2), the minimum Signal to Noise Ratio (SNR, being the ratio of the signals amplitude and the mean of the surrounding area in the amplitude spectrum) and the window size (defining the area around the peak, which SMURFS considers as a proxy for noise).

But what if i want to do a deeper analysis? SMURFS has you covered there as well and has loads of configurability and settings, allowing you to take a deeper look. For example, SMURFS can download/extract different data products, with different amount or reduction applied. You can specify, how the frequencies are fitted to the data, you can look at specific frequency ranges, you can fold and flatten your light curves and much more.

To get you started, you should first check the installation page, to make sure you have all prerequisites installed. Afterwards, take a look at the quickstart page, giving you a first easy example. Afterwards, feel free to roam this documentation and check out the different possibilities you have with SMURFS.
