Changelog

changes from 0.6.5 to 0.7.0

The primary change is that code developement has been moved to Github.

Also, in order to be more compliant with other astrophysical packages on Github (Astropy and SunPy) the directory layout has been changed and renamed.

The core routines are now imported as

import ChiantiPy.core as ch

this give access to ch.ion, ch.spectrum, etc.

In terms of bug-fixes, the calculation of excitation-autoionization cross-sections and rates have been corrected in the eaCross() and eaRate() methods

Current development is with Python 3.4

changes from 0.6.0 to 0.6.5

matplotlib.pyplot is now imported for plotting

IPython version 4 / Jupyter is now listed as a prerequisite. However, v0.6.4 can be made compatible with IPython 2 or 3 with a simple edit.

An error in calculating the proton excitation rates was fixed.

The code has been edited to make it compatible with Python 3 and has been tested against Python 3.3

changes from 0.5.3 to 0.6.0

This is a major release.

First, ChiantiPy 0.6.0 is compatible with the most recently released CHIANTI database version 8.0. It also fixes some major bugs in the previous version. Documentation has been improved and a IPython notebook QuickStart.ipynb, that largely follows the ‘Quick Start’ documentation pages, has also been included.

There are two new multi-ion classes: bunch and ipymspectrum. bunch allows the user to calculate line intensities for a specified set of elements or individual ions as a function of temperature or density. One advantage of bunch is the ability to calculate the intensity ratio of lines of two different ions as a function of temperature or density.

ipymspectrum is much like the existing spectrum and mspectrum classes. mspectrum allows the use of the Python multiprocessing module to speed up spectral calculations. The ipymspectrum class uses the IPython parallel module so that multiprocessing spectral calculations can be performed in the IPython QtConsole and Notebook.

A new method intensityList has been developed to allow the user to list the most intense lines within a given wavelength range. This new methods, together with previously existing intensityRatio and intensityRatioSave are all now inherited by the ion classs and the multi-ion classes.

The ion and multi-ion classes now accept the keyword argument abundanceName that allow the user to specify the set of elemental abundances rather than just the default abundance file.

Additional we have replaced the FortranFormat module of Scientific Python by Konrad Hinsen with the fortranformat module of Brendan Arnold at http://bitbucket.org/brendanarnold/py-fortranformat. I have slightly modified fortranformat to make it Python 3 compliant.

For the future, I plan to make ChiantiPy compliant with both Python 2.7 and the current version of Python 3 (now 3.4), improve the documentation and move the projec to github, in no particular order.

ChiantiPy is now released under a new license, the OSI approved ISCL license. From Wikipedia The ISCL license is a permissive free software license written by the Internet Software Consortium (ISC). It is functionally equivalent to the simplified BSD and MIT/Expat licenses, ...
