  It is shown in the paper that Pt activity limitation (modulus of the vector
sum) of all particle beyond "photon+Jet" system Pt^out leads to the noticeable
photon Pt - jet Pt disbalance decreasing. On a simultaneous restriction of the
cluster Pt and Pt^out from above it is possible to reach an acceptable balance
between photon Pt - jet Pt with a sufficient number of the photon Pt - jet Pt
events for the jet energy scale setting and hadron calorimeter calibratiom of
the CMS detector at LHC.
