Tool for the Planet Systems Imager to simulate the universe, generate planet spectra, evaulate instrument performance, and determine how well PSI can do science.

Features of psisim:

• Create various exoplanet populations using EXOSIMS (e.g., known RV planets, simulated planets following Kepler occurence rates),
• Simulate reflected and thermal emission spectra of gas giants and terrestrial planets using PICASO,
• Simulate planet fluxes based on evolutionary cooling models,
• Estimate polarized fluxes of exoplanets,
• Estimate performance of the AO system as a function of star brightness and ability to correct atmospheric turbulence,
• Handle detector noise, thermal emission, sky transmission, and
• Object oriented so easy to implement multiple sites and instruments.

First, install EXOSIMS and PICASO following the documentation for the respective packages.

Then pull this respository:

> git clone https://github.com/planetarysystemsimager/psisim.git

Move into that directory and run the setup.py script to install. Use the develop keyword to stay up to date with new changes:

> python setup.py develop
