Atomic Data Unleashed:
Interactive and scriptable interfaces to atomic databases
We present new software developed in ISIS, the Interactive Spectral Interpretation System, to provide high level access to underlying atomic data used in astrophysical plasma models. In particular, modules developed to support spectra computed from the XSTAR database allow for simple line or edge identification and more complex analysis requiring strengths or dependencies of specific features, such as theoretical line ratios. We will show examples for computing diagnostics of astrophysical interest, such as curves of growth and emissivity curves, and for modeling multi-component photoionized plamas (using warmabs and photemis) with newly developed ISIS modules. These software interfaces to atomic data are key to the legacy of Chandra, which has a rich and ever increasing high resolution spectroscopic dataset, requiring increasingly complex analysis.
