Multidimensional calibration of the EXOGAM segmented clover

The EXOGAM clover detector consists of four high-purity germanium (HPGe) crystals in a common cryostat. Each individual crystal is electrically segmented into four regions. We propose a method based on a multidimensional fitting procedure to calibrate the energy from the segments. This method could be used for any kind of segmented germanium detector. Its application to the EXOGAM clover is discussed in details.
