HD 85512 is TYC 7706-1752-1 !!!
See e.g. the Identifierer section of HD 85512 in Simbad:
Its also listed in the cat "HD identifications for Tycho-2 stars
(Fabricius+, 2002)" with the J2000 coords:
09 51 06.70 -43 30 06.1
The J2000 coords of the HD 85512 entry in VizieR are:
09 51.1 -43 29
which expants to:
09 51 06 -43 29 00
The J2000 coords of the TYC 7706-1752-1 entry in VizieR are:
09 51 07.052 -43 30 10.00
The J2000 coords of HD 85512 = TYC 7706-1752-1 in Simbad are:
09 51 07.05200 -43 30 10.0256
The J2000 coords of HD 85512b in Simbad are:
09 51 07.05 -43 30 10.0
so they are rounded J2000 coords of its host star.

Is the white cross (that doesn't point at HD 85512 = TYC 7706-1752-1)
at the coords of an object ?
If yes, then the entry the coords originate from must be wrong.
