20.7. SVD DataStore

Here we briefly describe the SVD objects that populate the DataStore.

class SVDEventInfo

StoreObjPtr created by SVDUnpacker / SVDEventInfoSetter and storing the following event-wise informations:

1. the DAQ mode (3-sample, 6-sample, 3-mixed-6 sample) of the run

2. the number of APV samples (3 or 6) in the acquired event

3. the TriggerBin

class SVDShaperDigit

StoreArray created by SVDUnpacker / SVDDigitizer and storing the raw strip informations:

1. layer, ladder, sensor (VxdID), side

2. cellID

3. amplitudes of the 6 samples. In case of 3-sample events, the last 3 values are set to zero

class SVDRecoDigit

StoreArray created by SVDRecoDigitCreator (not in default reconstruction) and storing the calibrated strip informations:

1. layer, ladder, sensor (VxdID), side

2. cellID

3. time and charge of the strip

class SVDCluster

StoreArray created by SVDClusterizer and storing the 1-D hit informations:

1. layer, ladder, sensor (VxdID), side

2. size, i.e. number of strips in the cluster

3. position, time and charge of the cluster

class SVDSpacePoint

StoreArray created by the SVDSpacePointCreator and storing the 3-d hit informations
