Detailed Description

template<typename T>
class RochesterCorrMuonProducerT< T >

Apply muon momentum corrections

NOTE: The muon momentum corrections account for residual differences in alignment between MC and data. The corrections are documented on the wiki http://www-cdf.fnal.gov/~jyhan/cms_momscl/cms_rochcor_manual.html and in CMS analysis notes AN-12/062 and AN-12/298.
