MuonPflowElementAccessor - Switch to dR calculation using pseudorapidity
Hi,
I was not aware that the xAODP4Helpers use the rapidity
instead of the pseudorapidity
by default.
inline
double deltaR( const xAOD::IParticle& p4, double rapidity, double phi, bool useRapidity=true )
{ return std::sqrt( xAOD::P4Helpers::deltaR2( p4, rapidity, phi, useRapidity ) ); }
That's clearly a bud. So instead of checking for positive pt like I came up earlier in !45266 (merged), the FPEs can of course be also avoided if we switch back to pseudorapidty which also restores the situation before !45076 (merged).
