measPhiBit

constexpr int8_t NrpcCablingOfflineID::measPhiBit = 1 << 0

staticconstexpr

gas gap -> 1-3

The BIL-RPC chambers have two strip-layers, both oriented to measure the eta coordinate. From a readout perspective, the strips share the same channel, despite that their readout positions are at opposite sides. In order to disentangle the particular sites of the strips, the second bit of the measPhi field is set.

Definition at line 50 of file NrpcCablingData.h.

phi

int8_t& NrpcCablingOfflineID::phi {m_cache.cache[2]}

Eta of the RPC station.

stationIndex

int8_t& NrpcCablingOfflineID::stationIndex {m_cache.cache[0]}
