Table 6:

The frequencies of confusion flavors of the observed scans (measurements) for each field and observing frequency.
Field	Clean	Cluster $^\star$	Confused	de-confused
	(%)	(%)	(%)	(%)
	4.85 GHz ( $FWHM\approx145\hbox{$^{\prime\prime}$ }$ )
02 $^{{\rm h}}$	59	18	23	4 (17)
08 $^{{\rm h}}$	57	18	25	9 (36)
14 $^{{\rm h}}$	60	20	20	4 (20)
20 $^{{\rm h}}$	59	19	22	6 (27)
Average	59	19	22	6 (27)
	10.45 GHz ( $FWHM\approx67\hbox{$^{\prime\prime}$ }$ )
02 $^{{\rm h}}$	92	1	7	0 (0)
08 $^{{\rm h}}$	93	2	5	0 (0)
14 $^{{\rm h}}$	90	1	9	2 (22)
20 $^{{\rm h}}$	92	2	6	1 (17)
Average	92	$\sim$ 1	$\sim$ 7	$\sim$ 2 (20)

It must be made clear that this result is based solely on the position of the dual-beam system in the sky and the spatial distribution of the field NVSS radio sources. In Col. 5 we give the fraction of the total number of scans that have been de-confused and in parenthesis the same number but as a fraction of the confused scans which is given in Col. 4.
$^\star$ Here the term cluster is meant to represent both, the cases of pure clustering flavour and those that are clustered and confused simultaneously.
