class AliITSOnlineSDDInjectors: public AliITSOnlineSDD

 default constructor

 standard constructor

 Destructor
 fHisto should not be deleted here because it points to an histo created
 by the external code which calls the method AnalyzeEvent
 if(fHisto) delete fHisto;

 Sets default values for parameters

 Sets specific parameters for 20 MHz running

 Sets specific parameters for 20 MHz running

 Sets drift distances for the 3 injector lines

 Resets all counters

 Analyze the current event

 Add the drift speed from current event to the average value

 Compute RMS of drift speed distribution on one anode

 Fits the average drift speed vs.anode number

 Builds the graph of drift time vs. drift distance

 Builds the graph of drift speed vs. anode number

 TGraphErrors with only pads with status of injector >= minAcceptStatus

 Get time zero from trigger signal

 fits the anode dependence of drift speed

 fits the anode dependence of drift speed with a polynomial function

 Computes the drift speed from the fit to the 3 injector lines for each anode

 Injectors location along anodes:
 Side left  (UP)   - channel 0: injectors on anodes 0,7,15,...,247,255
 Side right (DOWN) - channel 1: injectors on anodes 0,8,16,...,248,255

 Converts anode number into injector pad index

 returns an integer value with status of injector lines for given pad/anode
 status=7  -->  111  all injector are good
 status=6  -->  110  1st line (close to anodes) is bad, other two are good

 status=1  -->  001  only 1st line (close to anodes) good
 status=0  -->  000  all lines are bad

 Mark good injector pads
 good = 1 cell above high threshold + 1 neighbour above low threshold

 Computes the centroids (weighted mean) of teh injector pads

 Dumps the status bit of injector pads

 Dumps the drift time centroids of injector pads

 writes drift speed vs. anode fit parameters into an ASCII file
 to be sent to FXS by the DA and processed by the SHUTTLE

 Builds histogram of average drift speed vs. pad number

 Writes the output histograms into a root file

 dump status of injectors encoded into UInt_t
 5 bits (value 0-31) to store number of pads with given status
