The page for
HD 306209
shows two CPD identifiers: CPD-60 2697 (https://vizier.cds.unistra.fr/viz-bin/VizieR-5?-ref=VIZ65e0e9341d2c60&-out.add=.&-source=I/108/cpd&recno=381279) and CPD-60 3440 (https://vizier.cds.unistra.fr/viz-bin/VizieR-5?-ref=VIZ65e0e9331d2ac1&-out.add=.&-source=I/108/cpd&recno=382022). Looking at the coordinates and photometry in the CPD catalogue it is obvious that CPD-60 2697 (https://vizier.cds.unistra.fr/viz-bin/VizieR-5?-ref=VIZ65e0e9341d2c60&-out.add=.&-source=I/108/cpd&recno=381279) is not CPD-60 3440 (https://vizier.cds.unistra.fr/viz-bin/VizieR-5?-ref=VIZ65e0e9331d2ac1&-out.add=.&-source=I/108/cpd&recno=382022) (which is a star separated by 4.5º to the south and with a photometric difference of ~0.9 mag).
So,
CPD-60 3440 must be removed
from the list of identifiers of HD 306209 and given to the page of the star
TYC 8973-390-1
(which is in Simbad and does not currently include a CPD identifier).
