At this point, you have replaced the TH1D object you created
with another one generated by the ProjectionX() function call.
When you delete hd later in the code, you delete the ProjectionX()
object and not the one created by the 'new TH1D()' call.
Thus, the previous line 'TH1D* hd = new TH1D()' is not necessary.
Also, replace
hd = plot->ProjectionX("",50,50);
with
TH1D* hd = plot->ProjectionX("",50,50);
As for the difference in size of the leak, I do not know.
