1cm Smeared Distributions

[Yasir_Ali]

Dear Experts

I want to make X Y and Z distributions with 1cm smearing. Please check if this code and plots are correct if not Please suggest changes. Thanks

#include <TCanvas.h>
#include <TH1F.h>
#include <TRandom3.h>

void BS() {
  // Parameters
  const int numEntries = 1000;   // Number of entries
  const double mean = 0.0;       // Mean value
  const double smear = 1.0;      // Smearing value (in cm)

  // Create histograms to store the smeared distributions for x, y, and z
  TH1F* hSmearedX = new TH1F("hSmearedX", "Smeared Distribution (X);x (cm);Counts", 100, -10.0, 10.0);
  TH1F* hSmearedY = new TH1F("hSmearedY", "Smeared Distribution (Y);y (cm);Counts", 100, -10.0, 10.0);
  TH1F* hSmearedZ = new TH1F("hSmearedZ", "Smeared Distribution (Z);z (cm);Counts", 100, -10.0, 10.0);

  // Set up the random number generator for smearing
  TRandom3 randSmeared;

  // Fill the smeared histograms by adding Gaussian noise to the mean values for x, y, and z
  for (int i = 0; i < numEntries; i++) {
    double xSmeared = mean + randSmeared.Gaus(0.0, smear);
    double ySmeared = mean + randSmeared.Gaus(0.0, smear);
    double zSmeared = mean + randSmeared.Gaus(0.0, smear);

    hSmearedX->Fill(xSmeared);
    hSmearedY->Fill(ySmeared);
    hSmearedZ->Fill(zSmeared);
  }

  // Create a canvas and draw the histograms for x
  TCanvas* canvasX = new TCanvas("canvasX", "Distribution (X)", 800, 600);
  hSmearedX->Draw();
  canvasX->SaveAs("distributionX.png");

  // Create a canvas and draw the histograms for y
  TCanvas* canvasY = new TCanvas("canvasY", "Distribution (Y)", 800, 600);
  hSmearedY->Draw();
  canvasY->SaveAs("distributionY.png");

  // Create a canvas and draw the histograms for z
  TCanvas* canvasZ = new TCanvas("canvasZ", "Distribution (Z)", 800, 600);
  hSmearedZ->Draw();
  canvasZ->SaveAs("distributionZ.png");
}

May be @moneta can help.

@moneta and @Wile_E_Coyote Please guide me to check if the above code is correct to make random gaussian distribution with smearing of 1cm
