[73.11] Package for the Interactive Analysis of Line Emission: Markov-Chain and Monte Carlo Methods

V. L. Kashyap, L. Lin, J. J. Drake (Harvard-Smithsonian Center for Astrophysics)

We describe the implementation of Monte Carlo methods in the Package for Interactive Analysis of Line Emission (PINTofALE), which is a collection of IDL-based programs designed to analyze astrophysical spectra. We use Monte Carlo based methods to determine errors in spectral line parameters, and use Markov-Chain Monte Carlo methods to construct emission measure distributions which summarize the structure of the coronae of stars. We present examples of how the algorithms are used and discuss some planned updates.
