FeldmanCousins.C macro calculates upper limit on signal yield using the Feldman-Cousins approach. This follows the paper PRD V57 #7, p3873-3889. But this macro doesn’t take care of systematic uncertainty.
Is it possible for someone to include systematic uncertainty in upper limit estimation using this FeldmanCousins.C macro? There is a paper PHYSICAL REVIEW D 67, 012002 2003 that describes the upper limit by Feldman-Cousins approach including systematic uncertainty on background yield also.
Can anyone please change the existing FeldmanCousins.C macro or explain any other idea to estimate the upper-limit which takes care of the systematic uncertainty also in case of low statistics events?
