Int_t StEEmcPoint::numberOfRelatives ( )

Int_t StEEmcPoint::numberOfRelatives ( ) const

StEmcPoint* StEEmcPoint::stemc ( )

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

StEmcPoint * StEEmcPoint::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.
