Sensitivity of Line Emissivities to Atomic Uncertainties with PyAtomDB

With upcoming high-resolution X-ray spectroscopy missions such as XRISM and Athena, it is
important to quantify the impact that uncertainties on fundamental atomic quantities have on the
interpretation of observational X-ray spectra. We use the pyatomdb package to perturb ionization
and recombination rates as well as the direct excitation rates and A-values stored in the AtomDB
database to estimate final uncertainties on line emissivities and charge state distributions. We
implement plausible approximations to uncertainties in the underlying atomic data to provide
observers estimates of final uncertainties on spectral calculations.
