This looks great, and means that it's about time to redo some analysis.
Should I change any of the code to reflect your new calibrations?

I'm currently running the following (compilation...):

  // Get the Si/Tile calibrations
  BrTileTmpCalibration* tileCalib = BrTileTmpCalibration::Instance();
  BrSiTmpCalibration* siCalib = BrSiTmpCalibration::Instance();
  BrMultCentTmpCalibration * centCalib =
      BrMultCentTmpCalibration::Instance();

  //---- Module: Si readout module ----
  //-------- Calibrations currently not in database --------
  BrSiRdoModule *siRdoModule = new BrSiRdoModule("MultSi", "SiRdo");
  siRdoModule->SetOutlierMethod(BrSiRdoModule::kNoCorrection);
  siRdoModule->SetThresholdFactor(3.0);
  siRdoModule->SetMinVtx(-80.);
  siRdoModule->SetMaxVtx(80.);
  swModule->AddModule(siRdoModule);

  // ---- Module: Tile readout module ----
  // -------- Calibrations currently not in database --------
  BrTileRdoModule *tileRdoModule = new BrTileRdoModule("MultTile",
	"TileRdo");
  tileRdoModule->SetOutlierMethod(BrTileRdoModule::kNoCorrection);
  tileRdoModule->SetThresholdFactor(3.0);
  tileRdoModule->SetMinVtx(-80.);
  tileRdoModule->SetMaxVtx(80.);
  swModule->AddModule(tileRdoModule);

  BrMultCentModule * centModule = new
	BrMultCentModule("multcent","multcent");
  centModule->SetSiWeight(1.38);
  centModule->SetMaxMult(300);
  swModule->AddModule(centModule);
