detmap_config_file

The detmap_config_file contains the information about the hardware setup of the experiment. All channels of hardware are mapped to a long array called rawdet(). The structure of this file is as follows :

!
!  The format of the detector configuration file is described below.
!
!  There are seven entries per line.  There are three data types of entries:
!  integer, range, and character string.  There are two delimiters: the
!  exclamation mark "!", the dash "-" and the colon ":".  
!  The exclamation mark is used to mark the begining of a comments.  
!  All characters on a line following an "!"   are ignored.  
!  The "-", ":" or " " can be used to separate the 
!  low and high values in a  range entry.  
!  The seven entry classes are:
!
!           Entry Class           Data Type          
!   1.  Detector Name             character string    
!   2.  index                     integer          
!   3.  ROC #                     integer                   
!   4.  Crate Number              integer          
!   5.  Slot Number               integer       
!   6.  Channel Number            range                  
!   7.  Digitizer Model #         character string

The detectors can be separated into two groups, the detector array, which will map onto the rawdet() array, and the scaler_u type which will map onto rawscaler_u() array.

Each detector type will start mapping data onto the rawdet array at the RAWDET ARRAY INDEX. The length of the data from a particular module is given by CHANNEL RANGE. The module name is given by MODULE NAME. In the above example, data from module P7186 (which is a TDC) is mapped onto rawdet array at index 1. There are 4 channels of this detector type, hence the data will occupy rawdet(1),rawdet(2), rawdet(3), and rawdet(4). The module is located in CAMAC CRATE 1, SLOT 5. Since the rawdet() array is occupied up the element (4), the next available rawdet index is 5. Hence the next detector (EG&G 413 ADC) must be mapped starting a RAWDET ARRAY INDEX 5. It will occupy the array up to index 8. The 32 channel scaler P7132 will be mapped onto rawscaler_u() array starting at index 1 and will occupy the array up to index 33.
