Every Detector systems RCP file MAY have an RCP ARRAY named CERENKOV_LIST. This list specifies those tracking media that are used for Cerenkov light detection. The list is defined in mothers.rcp which defines all the media used in E907. The arguments are the same as for the routine gsckov.F

The routine gtckov.F has been modified by E907MC. The modified version is present in dd_geant.
