cds-question@unistra.frvariable-starsThe first seven extremely-red Haro-Chavira stars were published by Johnson et al. (1965ApJ...142.1249J), which includes BVRIJHKLMN photometry for them. The positions listed for these stars are consistently nearly a full degree in error, as a consequence of which they seem to have been overlooked in later literature. The offsets are parallel to the direction of precession, and the error evidently arises from the application of 100 years of precession motion with the wrong sign. These stars were unambiguously identified using the published charts, which are copied from the POSS-I prints of the region. In a follow-up work, Chavira (1967BOTT....4..197C) published a more extensive list of stars based on far-red objective-prism and direct plates. The main difficulty in the identifications was the poor positions, some in error by 10'. The finder charts were thus indispensable for positive identification on the sky. Two stars (HC 56 and HC 62) defeated my attempts to locate them.1999IBVS.4678....1Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/IBVS/4678CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/IBVS/4678https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/IBVS/4678http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/IBVS/4678https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/IBVS/4678https://vizier.iucaa.in/viz-bin/votable?-source=J/other/IBVS/4678http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/IBVS/4678GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/IBVS/4678/table1 (Positions and identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/IBVS/4678/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/IBVS/4678/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/IBVS/4678/table1?GETtext/xml+votable180.050000true308.5062542.4241670.0055555555555555565/7600 6/14338 14341 14351 14669 14680 14688 14691 14692 14693 28927 29091 29096 29098 29099 29269 29444 29446 29452 30240 30241 30242 30246 30249 30251 30252 30253 30255 30269 30270 30271 30312 30313 30314 30316 30318 30334 30356 30357 30359 30404 30405 30418 30421 30422 30423 30424 30425 30427 30430 30431 30449 30599 30604 30606 30616 30619 30622 30625 30628 30631 30641 30644 30645 30688 30690 30691 30713 30715 30718 30719 32064 32084 32086 32087 32092 320931.9821045660507152e-19 2.542825091373484e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/IBVS/4678?format=asciiOpticaldefaultJ/other/IBVS/4678/table1Positions and identificationsHCHC numbermeta.id;meta.mainintn_HC[*] indicates a note in notes.dat filemeta.notecharrecnoRecord number assigned by the VizieR team.
