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

Figure 2

SED for AME-G173.6+2.8, including flux densities at 0.408 and 1.42 GHz from the CGPSE catalogue, 2.7 GHz from Effelsberg, and 4.85 GHz from the GB6 catalogue corrected by the flux loss percentage of the AMI channel 3 observation and the flux-loss-corrected AMI fluxes. (a) shows flux densities corrected using the sampled CGPS map (blue) and using a simulated Gaussian source as a consistency check (red). Lower resolution flux densities are shown as triangles as they are considered to be upper limits. Also shown are the spectral index fits to CGPS 1.42 GHz and AMI together and to the blue AMI points separately. The inset plot is zoomed in to the AMI flux densities; here the errors plotted are the JMFIT error estimates only (without calibration uncertainty). (b) shows a free-free spectrum fit to the flux densities (see text for details).
