Higgs Combination Plot Update & Some Technical Points about Combining Sigmas

Abstract

ATLAS and CMS have updated their Higgs publications based on last years data. These results were released rapidly at the CERN council meeting in December but since then they have had time to polish the reports and as a bonus CMS have added some new data into the diphoton channels. Here I update my previous unofficial Higgs combinations and discuss some important technical points about combining sigmas.
