We introduce PLanetary Atmospheric Transmission for Observer Noobs (PLATON),
a Python package that calculates transmission spectra for exoplanets and
retrieves atmospheric characteristics based on observed spectra. PLATON is easy
to install and use, with common use cases taking no more than a few lines of
code. It is also fast, with the forward model taking much less than one second
and a typical retrieval finishing in minutes on an ordinary desktop. PLATON
supports the most common atmospheric parameters, such as temperature,
metallicity, C/O ratio, cloud-top pressure, and scattering slope. It also has
less commonly included features, such as a Mie scattering cloud model and
unocculted starspot corrections. The code is available online at
https://github.com/ideasrule/platon under the open source GPL-3.0 license.
