Notes. (1) Source name; (2) FIRST peak flux density. The quoted error is the rms is the noise in the FIRST map (mJy beam−1); (3) FIRST integrated flux density for the source; (4) NVSS integrated flux density with the mean error. N/A means that there is no NVSS flux available; (5) log(θ2), with . Sources with log(θ2) < 0.05 and ≥0.05 are classified as “unresolved” and “resolved” respectively (see text) in Col. (6); (7) : radio source size in arcsec measured from our new VLA data (8) . Sources with Δt < 0.35 and ≥0.35 are classified as “simple” and “complex” respectively in Col. (9). The Teacup was not part of our VLA sample. It is shown here because its radio properties are discussed in the text. (*)The NVSS flux of J0948+25 may be contaminated by a nearby source.
