Notes. Column 1 gives the identification numbers of the tapered images on which we have performed the measurements: ID 1: Image with source subtraction in uv-data; ID 2: Image without source subtraction in uv-data; ID 2 ss: Image of ID2 after removing by hand the flux of point sources identified in the image plane. Columns 2 and 3 correspond to the angular and physical size of the source, respectively (see text). Column 4 reports the flux of the diffuse radio sources as measured with TVSTAT within the 3 σ contours of the map with ID 2 (top), with TVSTAT within the 3σ contours calculated by PyBDSM for the map with ID 2 (bottom).
