Very high-energy SEDs measured with H.E.S.S., MAGIC, and VERITAS during the coordinated MWL campaign in 2018. Error bars are equivalent to the 1σ confidence level. An upper limit is drawn where the statistical significance is less than 2σ (i.e. 95% confidence level). The thick solid lines represent the best spectral fitting results by using a simple PL function. The shaded regions represent the 1σ error region of the fitting results. Historical spectral fits are taken from H.E.S.S. Collaboration (2006a,b), Aleksić et al. (2012), Acciari et al. (2008, 2010), Albert et al. (2008), Aliu et al. (2012), Beilicke & VERITAS Collaboration (2012), MAGIC Collaboration (2020) and the thin black line indicates the SED obtained with the MAGIC measurements presented in M87 MWL2017.
