VizieR Online Data Catalog: Faraday rotation of extended emission (Ordog+, 2019)
Abstract
The Rotation Measure (RM) map we present here was calculated using Stokes Q and U data from the Canadian Galactic Plane Survey polarisation dataset. The data were observed using the Dominion Radio Astrophysical Observatory Synthesis Telescope as part of the CGPS, in 4 frequency channels centred at 1407.2, 1414.1, 1427.7 and 1436.6MHz. We calculated RMs for the extended emission assuming a linear fit to polarisation angle as a function of wavelength squared. We then applied a filtering process as described in the paper. The size of the pixels in the map is 0.005 degrees by 0.005 degrees, and the entire map is 1825 by 29025 pixels, covering the CGPS longitude and latitude range.
