IXPE and contemporaneous multiwavelength polarization of PKS 2155−304. Panels from top to bottom are optical brightness, multiwavelength polarization degree, and multiwavelength polarization angle. The vertical gray shaded area demarcates the duration of the IXPE observation. Horizontal lavender shaded area in the bottom panel denotes the approximate position angle of the extended (> 1.5 pc) VLBI jet (see Sect. 1). The † symbol refers to host-galaxy-corrected values. To calculate ΠX/ΠO, we used the average host-galaxy-corrected ΠO in each of the two IXPE time bins.
