identToModuleIdx()

std::size_t NswT0Data::identToModuleIdx ( const Identifier & channelId ) const

private

The calibration data is internally stored as two jagged vectors, one for MM the other for sTGC.

The outer vector is sorted by the module index which is a composition of the detElementHash && the gasgap. Transform the channel identifier to the module Index

Parameters

channelId

Identifier of the channel to transform
