Hello good afternoon. I am representing a 3D graphic impact on the amount of photons on a surface and I have found that the flow distribution has a shape that does not correspond to the 3D graph. I attached pictures of the obtained and used Mathematica code Thanks you very much for your attention.

side[{photonID_, x_, y_, z_, sideID_}, refSide_] := sideID == refSide
file = FileNames["Receiver_*.dat"];
numberOfFiles = Length[file]
rReceiver = 0.045(*m*);
powerPerPhoton = 0.000348468 (*W/m2*);
nElements = 100;
ds = (2 rReceiver)/nElements (*m*);
dx = (2 rReceiver)/(nElements - 1) (*m*);
elementArea = ds*ds (*m^2*);
totalPhotonsCounts = ConstantArray[0, {nElements, nElements}];
totalNumberOfPhotons = 0;
totalNumberOfPhotonsX = 0;
totalPhotonsCountsX = ConstantArray[0, {nElements}];
rMin = 0.;
conversionFactor = powerPerPhoton/(elementArea*1000) (*MW/m2*);
For[i = 1, i <= numberOfFiles, ++i,
fileRawData = BinaryReadList[file[[i]], "Real64", ByteOrdering -> +1];
filePhotonSet = Partition[fileRawData[[1 ;; Length[fileRawData]]], 5];

Clear[fileRawData];
fileValidPhoton =Select[filePhotonSet, side[#, 0] &] /. {photonID_, x_, y_, z_, sideID_} -> {x, z};
fileValidPhotonX = Select[filePhotonSet,side[#, 0] &] /. {photonID_, x_, y_, z_, sideID_} -> {x};
Clear[filePhotonSet];
Print["Iteration # ", i, ". Processing file: ", file[[i]]] ;
     fileNumberOfValidPhotons = Length[fileValidPhoton];
     totalNumberOfPhotons = totalNumberOfPhotons + Length[fileValidPhoton];
     totalNumberOfPhotonsX = totalNumberOfPhotonsX + Length[fileValidPhotonX];

     filePhotonCounts =BinCounts[ fileValidPhoton, {-rReceiver, rReceiver, ds}, {-rReceiver, 
        rReceiver, ds}];
     filePhotonCountsX =  BinCounts[fileValidPhotonX, {-rReceiver, rReceiver, ds}];
     Clear[fileValidPhoton];
     totalPhotonsCounts = totalPhotonsCounts + filePhotonCounts;
     totalPhotonsCountsX = totalPhotonsCountsX + filePhotonCountsX;
     Clear[fileValidPhotonX];
     Clear[filePhotonCounts]
     Clear[filePhotonCountsX]]


    estimatedPowerAtReceiver =  powerPerPhoton totalNumberOfPhotons/1000 (*kW*)
fluxDistribution = conversionFactor*totalPhotonsCounts;
f2 = conversionFactor*totalPhotonsCountsX;
X = Range[-rReceiver, rReceiver, dx];
