Presentation of the detected targets listed in Table A.1. Each row shows a single target, labelled in the title of the first column. From left to right, the panels show (1) the VLA intensity map in mJy beam^-1 with black contours at [–10, –5,5,10,20,40,80,160] σ; (2) the map of the powerlaw spectral index, α, with 10 σ intensity contour overlaid; (3) the map of the l-σ absolute uncertainty in α, with a contour showing α = –0.5; and (4) the Effelsberg intensity map at 7.639 GHz (colour scale in mJy beam^-1) with VLA intensity contours overlaid and the beamsize shown for cases where it is not too large (in all cases, about 3 pixels in diameter). Also shown in the first panel are a line showing 1' scale at the bottom right, the synthetic beam FWHM at bottom left, blue dotted contours of WISE 22 pm emission, and a black arrow showing the direction of peculiar proper motion, where reliably estimated.
