Change a column of results summary

Hi,

I have find this code but i would like to delete a column “average size” and calculate an other value which is “count/ area of image”

run("Analyze Particles...", "display clear");
run("Distribution...", "parameter=Area automatic");
selectWindow("Area Distribution");
Plot.getValues(BinArray, CountArray);

selectWindow("Area Distribution");
run("Close");

if(isOpen("Results")){
  run("Clear Results");
  selectWindow("Results");
  run("Close");
}

Array.getStatistics(BinArray, MinBin, MaxBin, MeanBin, StdDevBin);
Array.getStatistics(CountArray, MinCount, MaxCount, MeanCount, StdDevCount);

MeanCount=round(MeanCount);
// Then I create a new array named Particle Size that includes only the Bin with a count higher than the meanCount
ParticleSize="";
for (Rown=0; Rown<CountArray.length; Rown++){
  Count=round(CountArray[Rown]);
  if(Count > MeanCount){
    ParticleSize=ParticleSize+round(BinArray[Rown])+"\n";
  }
}
ParticleSizeArray=split(ParticleSize,"\n");
Array.getStatistics(ParticleSizeArray, MinParticleSize, MaxParticleSize, MeanParticleSize, StdDevParticleSize);
// These are the values I was looking for MinParticleSize MaxParticleSize

// Now I can run the particle again but with the "best guess" values from the first analyze particle above
run("Analyze Particles...", "size=&MinParticleSize-&MaxParticleSize show=Overlay clear summarize");

Could you help me please ?
