MWL light curve for Mrk 421 covering the whole campaign from MJD 59695 (April 26, 2022) to MJD 59757 (June 27, 2022). The gray bands correspond to the three IXPE observations. Top to bottom: MAGIC fluxes in daily bins for two energy bands (note the two different y-axes); Fermi-LAT fluxes in 3 day bins; X-ray fluxes in daily bins including Swift-XRT, NuSTAR and IXPE; hardness ratio between the high- and low-energy fluxes of Swift-XRT and between the two VHE bands of MAGIC (note the two different y-axes); optical R-band data from NOT, RoboPol KANATA; IR H-band data from Perkins; radio data from IRAM and polarization degree and polarization angle observations in the optical to radio from NOT, RoboPol, KANATA, Perkins, IRAM, SMA and in X-rays from IXPE.
