Class Description

 Module to create reduce data objects form detector digits for the
 silicon strip detectors in the multiplicity array.

 The calculations is based on what Steve Sanders and Hiro Ito wrote
 in BAN26
 However, the centrality calculations are seperated out in a special
 module BrSiCentModule, as outline in BAN22

BrSiRdoModule (const Char_t *name, const Char_t *title) : BrMultRdoModule(name, title)

 Everyhting is done in BrMultRdoModule CTOR

void Init()

void Event(BrEventNode *inNode, BrEventNode *outNode)

void CalibrateIndividual(BrSiDig* dig, BrMultRdo* rdo)

 PRIVATE METHOD:
 Make the caibrated data for the individual detector elements
 i.e., each si.

 Please note, that the digit data is currently passed as a
 TObject, rather than a BrSiDig. This is so that we may read old
 files with BrDigSis objects in them. It will soon disappear.

Double_t CalibratePulser(Double_t calAdc)

 This function was modified for the year 2 runs by allowing for
 a zero offset of the pulser calibration.  This seems strange, but
 is found necessary to get a good fit for low pulser signals.

Year 1:
 Correct for the non-linearity of the silicon pulse shapers.
 This is done be applying the following piecewise (fork) function


         / f1(x) = a*x+bx^2                           for x < l1
         |
  f(x) = + f2(x) = f1(l1)+f1'(l1)*(x-l1) + c*(x-l1)^2 for x < l2
         |
          f3(x) = f2(l2)+f2'(l2)*(x-l2)              for x >= l2

 where a, b, c are calibration parameters.

Year 2:
 Correct for the non-linearity of the silicon pulse shapers.
 This is done be applying the following piecewise (fork) function


         / f1(x) = a + b*x+cx^2                       for x < l1
         |
  f(x) = + f2(x) = f1(l1)+f1'(l1)*(x-l1) + d*(x-l1)^2 for x < l2
         |
          f3(x) = f2(l2)+f2'(l2)*(x-l2)              for x >= l2

 where a, b, c,d  are calibration parameters.

Double_t CalibrateArrayMultiplicity()

 PRIVATE METHOD:
 Correct the sum multiplicity for the vertex position.
 This is based in on fits from GEANT, as far as I gather.
