 /**
  * @class AliHLTTPCClusterFinderComponent
  * Implementation of the cluster finder component.
  * The component implements the interface methods of the @ref AliHLTProcessor.
  * The actual cluster finding algorithm is implemented in @ref AliHLTTPCClusterFinder.
- * Two components are registered, TPCClusterFinderPacked and TPCClusterFinderDecoder.
- * TPCClusterFinderDecoder use the AliTPCRawStream class for decoding of the data, while TPCClusterFinderDecoder 
- * use the AliAltroDecoder for decoding the data.
- *
- * TPCClusterFinderDecoder is the fastest of the two, this is due to that the AliAltroDecoder
- * returns data in a bunch format. A bunch consist of consecutive signals.
- * TPCClusterFinderPacked first have to read the data one by one, which means that row, pad and
- * time signals have to be compared between each new digit, which leads to a slower alorithm. 
- * 
+ * Two components are registered, TPCClusterFinderUnpacked is for reading the HLT
+ * internal digit data format used in the simulation. TPCClusterFinder32Bit uses
+ * the AliHLTTPCDigitReader for raw data. After a phase of different decoder/raw stream
+ * implementations the CF for raw data is using the default offline raw stream for
+ * the 32bit RCU format AliAltroRawStreamV3, which also has a fall back to the 40bit
+ * AliAltroRawStream if the old RCU format is detected.
  *
  * The clusterfinder is now using the AliTPCTransform instead of the AliHLTTPCTransform for  
  * transformations from row, pad time -> x,y,z.
