Create stellar light curves!

Citlalicue

Oscar Barragán (Sept 2020)

Citlalicue is the name of the Aztec Goddess who created the stars. This code allows you to mimic Citlalicue powers to create and manipulate stellar light curves.

The actual version of the code allows you to create synthetic stellar light curves (transits, stellar variability and white noise) and detrend light curves using Gaussian Processes (GPs).

Dependencies:

• Numpy
• Matplotlib
• Scipy
• PyTransit
• george

Install it by typing

pip install citlalicue

Simulate light curves

Transits are implemented using PyTransit, while the stellar variability is added from samples of a Quasi-Periodic Kernel with covariance given by
