MWL LC for Mrk 501 between March 1, 2022, and July 19, 2022 (MJD 59639 to MJD 59779). The gray areas mark the IXPE observations from March 8-10, 2022 (MJD 59646 to MJD 59648), March 27-29, 2022 (MJD 59665 to MJD 59667), and July 9-12, 2022 (MJD 59769 to MJD 59772). Top to bottom: (i) MAGIC fluxes in daily bins, with the arrows displaying the upper limits (95% confidence level) for the non-significant bins (< 2 σ); (ii) Fermi-LAT fluxes in 7-day bins; (iii) X-ray fluxes in daily bins, including Swift-XRT, NuSTAR, and IXPE; (iv) hardness ratio between the high- and low-energy fluxes of Swift-XRT; (v) Swift-UVOT; (vi) optical R-band data from RoboPol, Calar Alto, T090, MAPCAT, T150, and AZT-8 in daily bins; (vii) radio data including OVRO, Metsähovi, IRAM, and SMA; and polarization degree (viii) and polarization angle (ix) observations in the X-rays from IXPE, the optical R band from NOT, RoboPol, Calar Alto, MAPCAT, T150, and AZT-8; and the radio band from IRAM and SMA. The IXPE and AZT-8 data are taken from Liodakis et al. (2022) and Lisalda (in prep.). In the polarization angle panel, we plot the average direction angle determined at 43 GHz by Weaver et al. (2022) with a horizontal gray band. See Sect. 4 for further details.
