MDC Analysis Scheme

The MDC analysis running fom raw data on hld level to fitted tracks with momentum determination and Vertex finding can be generalized as the following:

MdcDigitizerJochenMarkert (Class to simulate MDC response from GEANT MDC )

The HMdcDigitizer will read GEANT information about hits from HGeantMdc and convert them into drift time measurements folding in the response of the MDCs. For detailed informatio nof the different steps click on the header of the topic .

MdcCal1JochenMarkert (Offsets+Slopes)

In Data Analysis after unpacking the HMdcRaw level is filled. This data level contains the measured data in a hardware oriented way, which means the measured information is stored by hardware addresses sector, module, motherboard and tdc channel. The raw time measurements from the TDCs have to be converted to calibrated drift times, which will be later used for track reconstruction.
