lcsim

A python3 package to create artificial blazar light curves with a predefined power spectral density (PSD) and probability density function (PDF).

Requirements

The lcsim script uses the following standard python packages:

copy
math

The lcsim script uses the following python packages:

numpy
scipy
statsmodels

The simdb script uses the following standard python packages:

The simdb script uses the following python packages:

numpy
sqlite3

Getting Started

Get the python scripts:

$ git clone https://github.com/skiehl/lcsim.git

Open the jupyter notebook SimulationDemo.ipynb for a demonstation of the code. Either use jupyter lab:

$ jupyter lab

Or jupyter notebook:

$ jupyter notebook SimulationDemo.ipynb

Modules

lcsim.py: The main module for simulating light curves.
simdb.py: A SQLite3-based database backend to store simulations.
run_lcsim.py: A wrapper script to run and save light curve simulations for multiple sources.

Usage

Usage of the package is demonstrated in the jupyter notebook SimulationDemo.ipynb

Note: Documentation of the simdb.py module is not yet included.

A complete code documentation is given in html/.
