Investigating the Source of Planck-Detected AME: High-Resolution Observations at 15 GHz

Figure 1

(a) S235 and (b) S140. Visibilities sampled from CGPS 1.42 GHz data are plotted on the x-axis, with the corresponding AMI observed visibilities on the y-axis for channels 3 (blue points) and 8 (red points). The solid cyan and black lines show the respective ratios derived from fitting elliptical Gaussians to the maps, for example (integrated flux density from AMI channel map)/(integrated flux density from CGPS map sampled with corresponding AMI channel uv-coverage). There is a very good correlation between the sampled and true AMI visibilities, indicating that the morphology that AMI observes is very similar to that observed by CGPS.
