Table 2:

Fraction of $HK_{\rm s}L$ sources with a NIR excess. We also list the fraction derived by selecting only $HK_{\rm s}L$ sources whose $K_{\rm s}$ , after correction for reddening as explained in Sect. 4.3 ( $K_{\rm dered}$ ), is less than given thresholds (the selection criteria for L and $K_{\rm dered}$ are indicated in the first line).
	$L < L_{\rm compl}''$		$L < L_{\rm compl}$		$L < L_{\rm compl}$ and $K_{\rm dered} < 14$		$L < L_{\rm compl}$ and $K_{\rm dered} < 11$
