void RPCHitCleaner::run

(

)

Create cluster ids and store their size

hit belongs to cluster with clusterid

strip of i-1

for digicout

for chamber

Remove clusters with size>=4

Remove clusters with size>=4

keep only one bx per st/sec/wheel/layer

Count strips in a cluster

Keep clusters with size=2. Calculate and store the mean phi in RPCtoDTTranslator

for digicout

for chamber
