Clear message

The objective

The plan is: create a MarlinTPC processor chain that completely reflects the MultiFit reconstruction chain.

Use data taken with the MediTPC.

The processor chain

The first thing you need is the raw data from your detector. This LCIO file might have a single collection inside of the type Tracker'Raw'Data with the default name 'TPCRawData'.

In a table like fashion:

step

Processor name

Data output type

Default collection name

Conditions objects

1. Data conversion

TrackerRawDataToDataConverterProcessor

TrackerData

TPCConvertedData

Electronics

2. Pedestal Subtraction

PedestalSubtractorProcessor

TrackerData

TPCData

3. Pulse finding

PulseFinderProcessor

TrackerPulse

TPCPulses

4. Channel mapping

5. Hit finding

Conditions processing

For the chain to work several conditions objects are needed, although for now they may be implemented as processor parameters. The objects are commonly LCGenericObjects, defined in /tpcconddata Predefined:
