Hi everyone, pyXSIM has been updated to version 1.1.0. This version contains a bugfix and some minor new features. Fixed a bug which did not use the correct file names for AtomDB tables when using TableApecModel. Refactored the absorption model handling into a new class. No user-facing changes have been made. Added special classes for the TBabs and wabs absorption models. De-emphasizing XSpec-based spectral models in favor of the table-based alternatives. For more information see the website: http://hea-www.cfa.harvard.edu/~jzuhone/pyxsim http://hea-www.cfa.harvard.edu/~jzuhone/pyxsim pyXSIM can be installed in a few different ways. The simplest way is via the conda package if you have the Anaconda Python Distribution: [~]$ conda install -c jzuhone pyxsim The second way to install pyXSIM is via pip. pip will attempt to download the dependencies and install them, if they are not already installed in your Python distribution: [~]$ pip install pyxsim Alternatively, to install into your Python distribution from source (http://github.com/jzuhone/pyxsim http://github.com/jzuhone/pyxsim): [~]$ python setup.py install Thanks for using pyXSIM, John ZuHone
