This piece attempts to give an answer. The figure they give is 0.158 +/_ 0.096 which equates to between 0.062 and 0.254 degrees C. I admit I am not an expert in statistics but for such a small number the range seems huge with the second figure being over four times the first. I wonder if it is even possible to measure such a small amount with any certainty. It could not be noticed by humans using their senses.
