CHIANTI

An Atomic Database for Spectroscopic Diagnostics of Astrophysical Plasmas [DereLandiMason+97] [DereDelZannaYoung+19].

ChiantiIonReader

The ChiantiIonReader class is a wrapper for the ChiantiPy package that interacts directly with the database files and as a consequence uses a different notation. It provides information about individual ions.

ChiantiReader

The ChiantiReader class mimics the structure of GFALLReader and provides levels, lines and collisions tables for the selected ions.
