Significance maps of Mrk 421 (left panel) and Mrk 501 (right panel) for 1038 days of exposure, corresponding to energies above 0.5 TeV, obtained with HAWC data. The cross indicates the coordinates of the source, for Mrk 421 at R.A. = 166.11° and decl. = 38.2° (Fey et al. 2004), and for Mrk 501 at R.A. = 253.47° and decl. = 39.7° (Johnston et al. 1995), equatorial J2000.0.
