Dear mohamed noor, this could be noise, or due to missing low resolution reflections, due to fourier truncation errors, i.e. many things that you cannot really model. Given the seemingly medium resolution of your data you may leave it as is. If you can further improve your model at other places, this blob may go away.

Dear all
After refinement, there is a single negative peak in my map where nothing is modeled. What does it mean?
Thanks.
