Bool_t StEEmcIUPoint::chiSquare

(

const StEEmcIUPoint &

)

const

Chi2 sort method.

determine which of two points has the better "chi^2" between the two smd planes

StEEmcIUSmdCluster StEEmcIUPoint::cluster ( Int_t  c )

inline

Gets the specified cluster.

Parameters

c,:

0=U, 1=V

Definition at line 52 of file StEEmcIUPoint.h.

References mSmdClusters.

Int_t StEEmcIUPoint::numberOfRelatives ( )

inline

Return the number of "relative" points. A point is related if it lies within the 3x3 patch of towers centered on this point.

Definition at line 56 of file StEEmcIUPoint.h.

References mRelatives.

StEmcPoint * StEEmcIUPoint::stemc

(

)

Returns a pointer to a new StEmcPoint, basically a 1:1 copy of this point.

position error is a kludge, assumption is that we are accurate to within 1/2 of the molliere radius, R_{M}=2.0cm in Pb

endcap clusters are not used to determine point energy. towers + weighting function based on position to get point energy.
