We carry out Markov Chain Monte Carlo simulations to constrain the cosmological parameter space with the current CMB data for possible systematic effects! such as beam noncircularity in CMB measurements and incomplete sky coverage.enMethodsCos- mological parametersCosmic microwave backgroundArticle
