Phase-folded SED of the Crab P1 (black circles) and P2 (blue circles) measured by MAGIC between ~70 GeV and 1.5 TeV. The butterfly identifies the systematic uncertainty on the flux normalization and spectral index, whereas the arrow on the bottom right corner corresponds to an energy shift of 17%. The Crab Nebula spectrum (open squares) is also shown for comparison. The differential flux upper limits at 95% CL are computed under the assumption of the power-law spectrum measured in this work.
