More Data Exploration

These notebook tutorials show some ways to explore data with Stingray.

A quick look at a NuSTAR observation

Stingray transparently loads datasets from many HEASOFT-supported missions. In this Tutorial, we will show an example quicklook of a NuSTAR observation.

• Quicklook NuSTAR data with Stingray

A quick look of LAXPC data analysis

Stingray now can also read event files and GTI from AstroSat LAXPC mission. Here is a tutorial on how to load a test observation of Crab pulsar and work with various aspects of LAXPC observation (e.g. energy dependent analysis, layer dependent extraction, etc.)

• Imports
• Loading the event file.
• Filtering based on Units
• Filtering based on layer
• Energy dependent lightcurves
• Search of pulsations and folding
  • Power spectrum
  • Epoch folding search
  • Folding on the guess and best period

Studying very slow variability with the Lomb-Scargle periodogram

In this Tutorial, we will show an example of how to use the Lomb-Scargle periodogram and cross spectrum to study very slow variability in a light curve.

• Observations with frequent data gaps
• The Lomb-Scargle periodogram
• The Cross spectrum
