VHE spectrum of Mrk 501. The black circles are the HAWC (1038 days) data presented in this work. From the multiwavelength campaign performed in 2009 (Abdo et al. 2011b), the green crosses are from MAGIC (16.2 hr) and the light green squares are from VERITAS (9.7 hr). Also from that campaign, a high-activity state was reported by VERITAS (2.4 hr), and is shown with turquoise rightward triangles. The blue upward triangles and the magenta stars correspond to the spectra of VERITAS (2.6 hr) and MAGIC (1.3 hr), respectively, as reported in Acciari et al. (2011b). The yellow downward triangles correspond to the spectrum reported by the ARGO-YBJ experiment (1179.6 days) reported in Bartoli et al. (2012). The red leftward triangles are the data from the TACTIC telescope (129.25 hr) reported in Godambe et al. (2008).
