ChiantiPy

ChiantiPy is a Python interface to the CHIANTI atomic database for astrophysical spectroscopy. The CHIANTI atomic database for astrophysical spectroscopy provides the information necessary to calculate the emission spectrum from hot plasmas. ChiantiPy provides several top-level classes to access the database and calculate continuum and emission line intensities.

    Release Notes: This is another bugfix release. The methods and functions for calculating ionization cross section were never properly implemented, and this has been corrected. The calculation of ionization rate coefficients were performed correctly. Errors in the calculation of photo-excitation and stimulated emission have been corrected.

        Release Notes: This release accommodates the changes made in 7.1 of the CHIANTI atomic database. In addition, there is a new method "emissList" that allows one to print out a list of lines in a given wavelength range. Also, there is a new keyword "wvlRanges" for the chianti.ion.intensityRatio method that allows the user to determine intensity ratios for lines that are widely separated in wavelength. The documentation has been updated and describes these features in the "Quick-Start" guide.

          Release Notes: This is a bugfix release.

          •  02 Nov 2011 18:14

            Release Notes: Modifications have been made to remain compatible with the CHIANTI database Version 7.0. The structure of the ChiantiPy distribution has changed so that any version of ChiantiPy prior to 0.4.1 must be removed before installing the current version.
