position 
value 
meaning 
A 
0 
parallax value is strictly positive ($\varpi >0$) 
1 
parallax value is nonpositive ($\varpi \le 0$) such that extinction estimate
does not work 

2 
while $\varpi >0$ the parallax error is ${\sigma}_{\varpi}>1$mas 
B 
0 
both colours are close to the standard locus 
1 
below standard locus, i.e., $({G}_{\mathrm{BP}}G)>0.1$ and $$

2 
above standard locus, i.e., $(G{G}_{\mathrm{RP}})>(2.5\cdot (({G}_{\mathrm{BP}}G)+0.02))$ or 

$(G{G}_{\mathrm{RP}})>(0.5\cdot (({G}_{\mathrm{BP}}G)1.0)+1.1)$ 
C 
0 
$G{G}_{\mathrm{RP}}$ colour is inside union of ${T}_{\mathrm{eff}}$ and extinction training sets 
1 
$G{G}_{\mathrm{RP}}$ colour is smaller than union of ${T}_{\mathrm{eff}}$ and extinction training sets 
2 
$G{G}_{\mathrm{RP}}$ colour is larger than union of ${T}_{\mathrm{eff}}$ and extinction training sets 
D 
0 
${G}_{\mathrm{BP}}G$ colour is inside union of ${T}_{\mathrm{eff}}$ and extinction training sets 
1 
${G}_{\mathrm{BP}}G$ colour is smaller than union of ${T}_{\mathrm{eff}}$ and extinction training sets 
2 
${G}_{\mathrm{BP}}G$ colour is larger than union of ${T}_{\mathrm{eff}}$ and extinction training sets
