[submitted] xspec_emcee: XSPEC-friendly interface for the Python EMCEE package

XSPEC_EMCEE is an XSPEC-friendly interface for the pure-Python implementation of Goodman & Weare's Markov chain Monte Carlo (MCMC) Hammer (ascl:1303.002) that allows to carry out MCMC analyses of X-ray spectra in the X-ray spectral fitting program XSPEC (ascl:9910.005). This program is able to run multiple xspec processes simultaneously, speeding up the analysis. It requires Python (2.5 or higher), numpy, argparse, h5py, emcee (ascl:1303.002), and xspec (ascl:9910.005).
