Notes. Column (1): the ID number of each source from CLASC as given in Table A.1. Columns (2) and (7): the source area (S: in pixels) divided by the beam area (θbeam: in pixels), as measured by SEAC for the sources detected in the April 11 and April 26 epochs respectively. An indication of whether each source is resolved (Y) or not (N) is given in brackets following each measurement. Columns (3) and (8): the ratio of the integrated flux density (Sint) to the peak pixel flux density (Speak) of each of the CLASC sources (as measured by SEAC), for the April 11 and April 26 epochs respectively. Similarly to columns (2) and (7), an indication of whether each source is resolved (Y) or not (N) is given in brackets following each measurement (see Fig. 10 for further information). Columns (4) and (9): the convolved angular area of each CLASC source as measured from JMFIT, i.e. θmaj and θmin, divided by the beam area, i.e. bmaj and bmin, for the April 11 and April 26 epochs respectively. Columns (5)–(6) and (10)–(11): the major and minor axes of the deconvolved angular sizes of each of the sources within the CLASC, across both the April 11 and April 26 epochs. Size/θbeam has been measured within SEAC (i.e. down to a level of 3σ) and gives a quantitative measure of the source size in pixels compared to that of the beam size (θbeam). Major and minor axis measurements when given are deconvolved. LAS is the convolved largest angular size.
