Raw Data Format of Detectors

It is important that the numbers identifying the DDLs are unique. Therefore a unique number is assigned to each detector. This detector number times 0x100 is used as offset for the DDL IDs of each detector. The detector numbers and the DDL offsets are listed in the table below for all detectors. These values are just conventions and they may change in the future. Therefore it is recommended to use constants for these numbers in the code.

The detector names which are used to create the raw data DDL files are listed in the table below as well. In addition the total number of DDLs per detector is indicated and some links to documents describing the detector specific raw data are provided.
