Recently the IceCube collaboration confirmed the astrophysical neutrino flux in the muon neutrino channel with high significance using six years of data. This analysis used a likelihood approach with reconstructed muon energy and zenith angle as observables to measure the properties of the astrophysical muon neutrino flux. Additionally constraints on the prompt atmospheric neutrino flux from the decay of charmed mesons were obtained. In this contribution we will present an update to this analysis using eight years of data collected from 2009 through 2017, containing about 500,000 muon neutrino candidates with a negligible contribution of atmospheric muons.
