21 Source 21 may also have lost flux as a result of resolution at 8.5 GHz.
27 Source 27 was a clear double and resolved in our 4.8GHz image, but only one 
27  of the two components was (marginally) visible at 8.5 GHz. In calculating 
27  the 4.8-8.5GHz spectral index, we compared 8.5 and 4.8 GHz flux densities of
27  that component only.
41 Two sources, 41 and 43, were clearly multiple. In these cases, we summed the
41  flux density from the two or three components of each source and treated 
41  each of the extended objects as a single entry in the source counts.
43 Two sources, 41 and 43, were clearly multiple. In these cases, we summed the
43  flux density from the two or three components of each source and treated 
43  each of the extended objects as a single entry in the source counts.
