SPISEA: A Python-based Simple Stellar Population Synthesis Code for Star Clusters

SPISEA (Stellar Population Interface for Stellar Evolution and Atmospheres) is a python package that generates single-age, single-metallicity populations (i.e. star clusters). It gives the user control over many parameters:

• Cluster characteristics (age, metallicity, mass, distance)
• Total extinction, differential extinction, and extinction law
• Stellar evolution and atmosphere models
• Stellar multiplicity and Initial Mass Function
• Initial-Final Mass Relation
• Photometric filters

Here is a brief list of things that SPISEA can do:

• make a cluster isochrone in many filters using different stellar models
• make a star cluster at any age with an unusual IMF and unresolved multiplicity
• make a spectrum of a star cluster in integrated light 

Code is available for download via Github (https://github.com/astropy/SPISEA) and documentation is available via ReadtheDocs (https://spisea.readthedocs.io/en/latest/index.html).
