 Another re ‐ analysis found no clear evidence for a fifth planetary signal in the combined HIRES / HARPS data set . The claim was made that the HARPS data provided only some evidence for 5 planet signals , while incorporation of both data sets actually degraded the evidence for more than four planets ( i.e. , none for 581 f or 581 g ) . Mikko <unk> of the University of Hertfordshire performed a Bayesian re @-@ analysis of the HARPS and HIRES data with the result that they " do not imply the conclusion that there are two additional companions orbiting GJ 581 " .
