Detailed Description

Descriptor for regions of the electromagnetic barrel calorimeter.

This class describes completely the segmentation in eta and phi, and also the depth boundaries of cells within a region of the EMB. This descriptor does not need to ever be accessed directly. If you are tempted to use it directly, look first at the EMBDetectorRegion and the EMBCell class. EMBCells obtained from a EMBDetector Region is normally a preferred way to access all of the information in the EMBDetDescr class.

m_halfLength

m_offset

std::vector<double> EMBDetDescr::m_offset

private

Vector of cell center positions for the cells, one for each eta index.

These numbers are relative to the front face of the EMEC active volume. This happens to be the z=0 face of the local coordinate system in the EMEC, but that little detail depends critically on the way the Geo Model description is implemented and may be false by the time you read this comment. For the presampler the offset is relative to the middle of the presampler active volume, which is also z=0 for the presampler local coordinate (with the same caveats as above).

(From the database table EmecSamplingSep and other related tables.)
