Image Details
Caption: Figure 4.
VLBA images of 1ES 1959+650 at 7 mm at three epochs contemporaneous with the IXPE observations. Contours: total intensity in factors of 2, starting at 2% of the peak intensity of (left to right) 0.16, 0.12, and 0.14 Jy beam−1. Color coding: relative linearly polarized intensity, with maxima of (left to right) <4, 2.8, and 4.0 mJy beam−1. Yellow line segments: electric-vector position angle of polarization. Cross-hatched ellipse in the lower left of each panel: FWHM of the elliptical restoring beam corresponding to the angular resolution along different directions. All positions are relative to the location of maximum intensity.
