Notes. The last two columns give the flux density and background measurements of the 15 GHz and 43 GHz polarization data. Also listed are the flux and background measurements in the lower frequency bands, after repositioning the photometric aperture to account for the shift in hotspot position detailed in Sect. 3.3.
Shifted aperture position. See Sect. 3.3 for details.
