摘要：

We introduce a Markov chain Monte Carlo simulation and data analysis package that extends the Cmbeasy software. We have taken special care in implementing an adaptive step algorithm for the Markov chain Monte Carlo in order to improve convergence. Data analysis routines are provided which allow one to test models of the Universe against measurements of the cosmic microwave background, supernovae Ia and Large Scale Structure. We present constraints on cosmological parameters derived from these measurements for a LambdaCDM cosmology and discuss the impact of the different observational data sets on the parameters. The package is publicly available as part of the Cmbeasy software at www.cmbeasy.org.
