Table A.1.

Handling of missing detections.

M₁	M₂	M₁ − M₂	M₁/M₂
NaN	27.17	NaN	NaN
25.72	NaN	NaN	NaN
NaN	NaN	NaN	NaN

M₁	M₂	M₁ − M₂	M₁/M₂


$M_{1}^{(2 σ)}$ $M_1^{(2\sigma)}$	27.17	$M_{1}^{(2 σ)}$ $M_1^{(2\sigma)}$	$M_{1}^{(2 σ)}$ $M_1^{(2\sigma)}$
25.72	$M_{2}^{(2 σ)}$ $M_2^{(2\sigma)}$	$- M_{2}^{(2 σ)}$ $- M_2^{(2\sigma)}$	$1 / M_{2}^{(2 σ)}$ $1/{M_2^{(2\sigma)}}$
$M_{1}^{(2 σ)}$ $M_1^{(2\sigma)}$	$M_{2}^{(2 σ)}$ $M_2^{(2\sigma)}$	NaN	NaN

Notes. Three examples of data points (rows) with non-detections to clarify the missing numbers handling adopted in this work. The upper table indicates the original values of magnitudes, colours and ratios, while the lower table give the corresponding values after the missing detection handling. M₁ and M₂ indicate two different bands magnitudes, while $M_{1}^{(2 σ)}$ $M_1^{(2\sigma)}$ and $M_{2}^{(2 σ)}$ $M_2^{(2\sigma)}$ are their 2σ detection limits, as reported in Table 1.
