libpypsg 0.4.0

A Python library for accessing the Planetary System Generator.

A Python library to interact with the Planetary Spectrum Generator.

The goal of this package is to make PSG more accessible to new users, but still be powerful enough that expert users will find it useful.

In the simplest use case, users can create a PSG config file from scratch using the PyConfig class.

import libpypsg

cfg = libpypsg.cfg.PyConfig(
    target=libpypsg.cfg.Target(object='Exoplanet',name='Proxima Cen b')
    )
print(cfg.content)

b'<OBJECT-NAME>Proxima Cen b\n<OBJECT>Exoplanet'

We can then call PSG with our setup.

psg = libpypsg.APICall(
        cfg=cfg,
        output_type='rad',
    )
response = psg()

Now let’s take a look at the rad file we get back. The PyRad class inherits from astropy.table.QTable.

rad = response.rad
