fiasco

Powered by SunPy Badge Build Status Documentation Status Coverage Status

A Python interface to the CHIANTI atomic database. For a high level overview of the package, have a look at my talk (slides, video) from the 2018 Python in Astronomy conference.

DISCLAIMER: fiasco is still in the very early stages of development. As such, the API is changing very frequently and drastically.

Dependencies

All packages can be installed with conda (recommended)

$ conda install {package_name}

or pip

$ pip install {package name}
  • NumPy
  • scipy
  • Astropy
  • h5py
  • PlasmaPy (pip only, conda soon)
  • fortranformat (pip only)

The CHIANTI atomic database is also required.

Install

$ git clone https://github.com/wtbarnes/fiasco.git
$ cd fiasco && python setup.py install

Example

>>> import astropy.units as u
>>> import fiasco
>>> iron = fiasco.Element('iron', [1e4, 1e6, 1e8]*u.K)
# Print some information about the element
>>> iron.atomic_number
26
>>> iron.atomic_symbol
'Fe'
>>> iron.abundance
<Quantity 3.16227766e-05>
# Select the Fe 16 ion
>>> iron[15].ion_name
'Fe 16'
>>> iron[15].charge_state
15
# Ionization fraction
>>> iron[15].ioneq
<Quantity [0.000e+00, 2.377e-08, 4.163e-18]>

Why fiasco?

A fiasco, or flask, is the typical style of bottle used to serve the Chianti Classico wine. It is typically larger and rounder at the bottom and is covered by a straw basket. In the same way, the fiasco package serves up the CHIANTI atomic database.
