Images of G16.8−1.1. The contours display the total intensity at λ6 cm, starting at 50 mK T_B and running in steps of 50 mK T_B. The image shows the observed λ6 cm polarization intensity in the top panel, the Hα intensity in the middle panel, and the absolutely calibrated λ6 cm polarization intensity in the bottom panel. The bars indicate B-vectors with their lengths proportional to polarized intensity with a low intensity cutoff of 1 mK T_B. The box indicates the mapped region by Reich et al. (1986). The star indicates the position of the pulsar PSR B1822−14.
