Detailed Description

Descriptor for regions of the hadronic endcap calorimeter.

This class describes completely the segmentation in "eta" and phi. Eta appears in quotes because the HEC does not have eta boundaries, it has a staircase of radial boundaries that roughly adhere to an eta value. Keeping that in mind, this region describes the phi granularity of a region of the HEC and the radial and longitudinal division of the cells within the HEC. This descriptor does not need to ever be accessed directly. If you are tempted to use it directly, look first at the HECDetectorRegion and the HECCell class. HECCells obtained from a HECDetectorRegion is normally a preferred way to access all of the information in the HECDetDescr class.
