class AliTRDmcmSim: public TObject

 AliTRDmcmSim default constructor
 By default, nothing is initialized.
 It is necessary to issue Init before use.

 AliTRDmcmSim destructor

 Initialize the class with new MCM position information
 memory is allocated in the first initialization

 Resets the data values and internal filter registers
 by re-initialising them

 Reallocate memory if a change in the number of timebins
 is needed (should not be the case for real data)

 loads the ADC data as obtained from the digitsManager for the specified MCM.
 This method is meant for rare execution, e.g. in the visualization. When called
 frequently use SetData(...) instead.

 This function can be used to test the filters.
 It feeds nsamples of ADC values with a gaussian distribution specified by mean and sigma.
 The filter chain implemented here consists of:
 Pedestal -> Gain -> Tail
 With inputGain and inputTail the input to the gain and tail filter, respectively,
 can be chosen where
 0: noise input
 1: pedestal output
 2: gain output
 The input has to be chosen from a stage before.
 The filter behaviour is controlled by the TRAP parameters from AliTRDtrapConfig in the
 same way as in normal simulation.
 The functions produces four histograms with the values at the different stages.

 Check whether object is initialized

 Prints the data stored and/or calculated for this MCM.
 The output is controlled by option which can be a sequence of any of
 the following characters:
 R - prints raw ADC data
 F - prints filtered data
 H - prints detected hits
 T - prints found tracklets
 The later stages are only meaningful after the corresponding calculations
 have been performed.

 Plots the data stored in a 2-dim. timebin vs. ADC channel plot.
 The option selects what data is plotted and can be a sequence of
 the following characters:
 R - plot raw data (default)
 F - plot filtered data (meaningless if R is specified)
 In addition to the ADC values:
 H - plot hits
 T - plot tracklets

 Store ADC data into array of raw data

 Store ADC data into array of raw data

 Set the ADC data from an AliTRDarrayADC

 Set the ADC data from an AliTRDarrayADC
 (by pad, to be used during initial reading in simulation)

 Store ADC data into array of raw data

 retrieve the MC hit information (not available in TRAP hardware)

 Return column id of the pad for the given ADC channel

 Produce raw data stream from this MCM and put in buf
 Returns number of words filled, or negative value
 with -1 * number of overflowed words

 Produce tracklet data stream from this MCM and put in buf
 Returns number of words filled, or negative value
 with -1 * number of overflowed words

 Filter the raw ADC values. The active filter stages and their
 parameters are taken from AliTRDtrapConfig.
 The raw data is stored separate from the filtered data. Thus,
 it is possible to run the filters on a set of raw values
 sequentially for parameter tuning.

 Initializes the pedestal filter assuming that the input has
 been constant for a long time (compared to the time constant).

 Returns the output of the pedestal filter given the input value.
 The output depends on the internal registers and, thus, the
 history of the filter.

 Apply pedestal filter

 As the first filter in the chain it reads data from fADCR
 and outputs to fADCF.
 It has only an effect if previous samples have been fed to
 find the pedestal. Currently, the simulation assumes that
 the input has been stable for a sufficiently long time.

 Initializes the gain filter. In this case, only threshold
 counters are reset.

 Apply the gain filter to the given value.
 
 The output depends on the internal registers and, thus, the
 history of the filter.

 Read data from fADCF and apply gain filter.

 Initializes the tail filter assuming that the input has
 been at the baseline value (configured by FTFP) for a
 sufficiently long time.

 Returns the output of the tail filter for the given input value.
 The output depends on the internal registers and, thus, the
 history of the filter.

 Apply tail cancellation filter to all data.

 Zero Suppression Mapping implemented in TRAP chip
 only implemented for up to 30 timebins

 See detail TRAP manual "Data Indication" section:
 http://www.kip.uni-heidelberg.de/ti/TRD/doc/trap/TRAP-UserManual.pdf

 Add the given hit to the fit register which is lateron used for
 the tracklet calculation.
 In addition to the fit sums in the fit register MC information
 is stored.

 Preprocessing.
 Detect the hits and fill the fit registers.
 Requires 12-bit data from fADCF which means Filter()
 has to be called before even if all filters are bypassed.

 Select up to 4 tracklet candidates from the fit registers
 and assign them to the CPUs.

 Perform the actual tracklet fit based on the fit sums
 which have been filled in the fit registers.

 Run the tracklet calculation by calling sequentially:
 CalcFitreg(); TrackletSelection(); FitTracklet()
 and store the tracklets

 store the found tracklets via the loader

 write back the processed data configured by EBSF
 EBSF = 1: unfiltered data; EBSF = 0: filtered data
 zero-suppressed valued are written as -1 to digits

 return PID calculated from charges accumulated in two time windows

 This function adds a and b (unsigned) and clips to
 the specified number of bits.

 Additional baseline which is added for the processing
 in the TRAP and removed when writing back the data.
 This is needed to run with TRAP parameters set for a
 different baseline but it will not change the baseline
 of the output.
