fiasco 0.5.0

A Python interface to the CHIANTI atomic database

fiasco

fiasco provides a Python interface to the CHIANTI, an atomic database used primarily for astrophysical spectroscopy. In addition to several high-level abstractions of the atomic data, fiasco also provides many common atomic physics calculations.

Install

pip install fiasco

The CHIANTI atomic database is also required. See the docs for more details.

Usage

The primary interface in fiasco is the Ion object:

>>> import fiasco
>>> import astropy.units as u
>>> fe_18 = fiasco.Ion('Fe XVIII', 1*u.MK)
>>> fe_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.
