AtomNeb

Atomic Data for Ionized Nebulae

What is AtomNeb?
AtomNeb is an atomic database useful for nebular spectral analysis, plasma diagnostics, and abundance analysis. AtomNeb includes energy levels (Ej), collision strengths (Ωij), and transition probabilities (Aij) of the most ions commonly observed in ionized nebulae. AtomNeb uses the Flexible Image Transport System (FITS) format to store atomic data.
How can I use AtomNeb?
AtomNeb needs to read the atomic data written in the FITS file format. There are the three main functions for reading energy levels (Ej), collision strengths (Ωij), and transition probabilities (Aij), namely atomneb_read_elj(), atomneb_read_omij(), and atomneb_read_aij().
What are the system requirements for AtomNeb?
AtomNeb requires the Interactive Data Language (IDL) compiler developed by ITT Exelis Visual Information Solutions (ITT Exelis VIS).
