20 Simple calorimeter digitizer Processor.
21 === SimpleCaloDigi Processor === <br>
22  * Simple calorimeter digitizer Processor. <br>
23  * Takes SimCalorimeterHit Collections and <br>
24  * produces CalorimeterHit Collections. <br>
25  * Simulated energy depositions in active <br>
26  * layers of calorimeters are <br>
27  * converted into physical energy. This is done <br>
28  * taking into account sampling fractions of <br>
29  * ECAL and HCAL. <br>
30  * User has to specify ECAL and HCAL SimCalorimeterHit <br>
31  * collections with processor parameters <br>
32  * HCALCollections and ECALCollections. <br>
33  * The names of the output CalorimeterHit Collections <br>
34  * are specified with processor parameters <br>
35  * ECALOutputCollection and HCALOutputCollection. <br>
36  * Conversion factors for ECAL and HCAL <br>
37  * are specified via processor parameters <br>
38  * CalibrECAL and CalibrHCAL. <br>
39  * It should be noted that ECAL and HCAL may consist <br>
40  * of several sections with different sampling fractions. <br>
41  * To handle this situation, calibration coefficients for <br>
42  * ECAL and HCAL are passed as arrays of floats with each element <br>
43  * in this array corresponding to certain section with <br>
44  * a given sampling fraction. <br>
45  * List of layer numbers terminating each section are given through <br>
46  * processor parameters ECALLayers and HCALLayers <br>
47  * There is an option to perform digitization of <br>
48  * both ECAL and HCAL in a digital mode. <br>
49  * Digital mode is activated by <br>
50  * setting processor parameters <br>
51  * IfDigitalEcal / IfDigitalHcal to 1. <br>
52  * In this case CalibrECAL / CalibrHCAL will <br>
53  * convert the number of hits into physical energy. <br>
54  * Thresholds on hit energies in ECAL and HCAL <br>
55  * are set with processor parameters <br>
56  * ECALThreshold and HCALThreshold. <br>
57  * Relations between CalorimeterHits and SimCalorimeterHits <br>
58  * are held in the corresponding relation collection. <br>
59  * The name of this relation collection is specified <br>
60  * via processor parameter RelationOutputCollection. <br>
61  * <h4>Input collections and prerequisites</h4>
62  * SimCalorimeterHit collections <br>
63  * <h4>Output</h4>
64  * CalorimeterHit collections for ECal and HCal. <br>
65  * Collection of relations <br>
66  * between CalorimeterHits and SimCalorimeterHits. <br>
67  * For ECal Calorimeter hits the variable type is set to 0, <br>
68  * whereas for HCal Calorimeter hits the type is set to 1 <br>
