VHE spectrum of Mrk 421. The black circles correspond to the data from HAWC (1038 days). The green crosses are the MAGIC data for the 4.5 month observation campaign in 2009 (Abdo et al. 2011a). The rightward yellow triangles are the ARGO-YBJ data for a 4.5 yr period between 2008 and 2012 (Bartoli et al. 2016). The orange diamonds are the 676 days of observations with the ARGO-YBJ experiment between 2007 and 2010 (Bartoli et al. 2011). The pink upward triangles are from the 25.6 hr of observations performed with MAGIC between 2004 and 2005 (Albert et al. 2007a). The blue downward triangles, cyan stars, and light blue squares correspond to observations performed by VERITAS telescopes for a very low (7.83 hr), low (16.3 hr) and mid states (7.79 hr), respectively (Acciari et al. 2011a).
