[27.05] PINTofALE: Package for the Interactive Analysis of Line Emission

V.L. Kashyap, J.J. Drake (SAO)

We have developed an IDL-based package for the analysis of high-resolution grating spectra from coronal sources in the 1-1500~Å\ range. It is designed to flexibly query different atomic databases, identify spectral lines, measure fluxes, and carry out detailed modeling. It thus allows the exploitation of all the available diagnostic information in a high-resolution spectrum that can only realistically be achieved through detailed line-by-line analyses and with a hands-on approach to the relevant atomic data. We are now making a version of this package available for general use.

Because of the interactive nature of the analysis, the package is structured into 2 main groups of routines: those which read externally compiled atomic datasets and recast them into a uniform format, and those that manipulate the databases and carry out the analyses. The latter includes a spectral browser to identify features in the spectra, and a GUI-controlled fitting engine to measure line fluxes.

We show examples of usage with specific examples as applied to Chandra grating data of the RS CVn binary HR1099.
