The Interactive Spectral Interpretation System(ISIS) is designed to facilitate theinterpretation and analysis of high resolutionX-ray spectra. It is being developed as aprogrammable, interactive tool for studying thephysics of X-ray spectrum formation, supportingmeasurement and identification of spectralfeatures and interaction with a database of atomicstructure parameters and plasma emission models.License: GNU General Public License (GPL)Changes:
Loading of xspec12 local models was enabled. Support for the S-Lang debugger and profiler was added. The create_aped_line_modifier now supports modifiers that take additional user-defined arguments. xspec table models now load parameter defaults from the table file. Support for the analysis of INTEGRAL data was added. The performance of APED spectral models that use a line modifier was improved. The code was cleaned up and bugs were fixed.
