void AliTPCCalibPedestal::SetTimeAnalysis ( Bool_t  time = kTRUE)

Use time dependent analysis: Pedestals are analysed as a function of the drift time. There is one mean value generated for each time bin and each channel. It can be used as reference data and for configuration of the ALTRO pattern memory for baseline subtraction.

ATTENTION: Use only on LDC in TPCPEDESTALda! On a LDC we get data only from one sector. For the full TPC we would need a lot of memory (36*159*140*1024*4bytes = 3.3GB)!
